- This paper reports the selective fabrication of a zeolitic imidazolate framework-8 (ZIF-8) cover layer over the outer surface of silica hard-shell microcapsules (HSMC) to improve the microencapsulation technique of phase change materials for heat storage materials. ZIF-8 was formed not only over the HSMC but also in the synthesis solution side when using a conventional batch operation owing to the rapid formation rate of ZIF-8 in the aqueous solution at 293 K. In this study, a semi-batch operation, which can control the concentration of the components in the synthesis solution by gradually dropping the components, was employed to decrease the formation rate of ZIF-8. X-ray diffraction results suggested that dropping ingredients strongly affected the obtained products; the addition of the Zn2+ aqueous solution into a 2-methylimidazole (Hmim) aqueous solution was suitable for the formation of ZIF-8, whereas the addition of an aqueous solution of Hmim into the Zn2+ aqueous solution formed Zn hydroxides as unfavorable by-products. Field-emission scanning electron microscopy and energy-dispersive X-ray spectroscopy results confirmed that the semi-batch operation with the addition of Zn2+ into the Hmim aqueous solution selectively formed a ZIF-8 cover layer over the HSMC. We conclude that the semi-batch operation is an effective procedure for suppressing the unfavorable homogeneous nucleation on the solution side and making heterogeneous nucleation dominant without any additives to fabricate the ZIF-8 cover layer.2022年09月, CrystEngComm, 24(42) (42), 7378 - 7386研究論文（学術雑誌）
- In the film formation process of latex paints, polymer particles accumulate and deform with stress relaxation and then coalesce into a continuous film. Our previous studies clarified the differences in particle-packed structure formation between drying temperatures by the accurate measurement of water content. In the present study, we investigate the mechanism of stress development for latex coating from viewpoints of particle accumulation and deformation by the simultaneous measurements of drying stress and water content. When a particle-packed layer forms on the surface side of the coating during the constant drying rate period, it is found that the stress development is proportional to the amount of the packed layer. Even for deformable particles at higher drying temperatures, the proportionality can be held, but the stress relaxation becomes noticeable at a high moisture content exhibiting a gradual decrease in the drying rate. After the complete formation of the closest-packed layer, it is revealed that the shrinkage of the layer causes additional stress development. We then proposed a model where the stress development is described by the shrinkage of the packed layer and the stress relaxation by the temperature dependency of polymer deformability.2022年09月, Progress in Organic Coatings, 170研究論文（学術雑誌）

- Background: A rotationally reciprocating impeller separates the horizontal cross-section of the vessel into two mixing regions under a laminar flow regime. In this study, we investigated the separation mechanism from the dynamics of the streakline on the boundary Methods: The stretching behavior of the streakline on the universal boundary of active mixing regions was successfully visualized by injecting tracer fluid from a specific position Findings: The elongational rate of streakline proportionally increased with the increase in Reynolds number. Besides, the linear component of the elongation rate drastically changed at Re∼10 due to the bending of the boundary. Compared with other chaotic mixing flows, we proved that tracer particles are enclosed in turnstile lobes at the hyperbolic fixed point at the wall, transported on the boundary, namely separatrix, to the mixing shaft being another hyperbolic fixed point, and then distributed evenly into both mixing regions. It was concluded that the boundary becomes wavy at Re > 10, which increases the area of turnstile lobes to enhance fluid transportation between two mixing regions2022年02月, Journal of the Taiwan Institute of Chemical Engineers, 131研究論文（学術雑誌）
- In analogy to momentum, heat, and mass transfer, the friction factor at the sidewall plays a crucial role in transport phenomena in chemical processes using agitated vessels. The present work numerically investigated the distribution of the friction factor in a turbulent agitated vessel with the aid of a computational fluid dynamics simulation. The numerically obtained velocity distribution for a paddle impeller showed a good agreement with experimental and theoretical values, which indicated that the numerical procedure was reliable. A circulation flow induced by a MAXBLEND impeller was deformed by adding baffle clearance, and a more complex flow pattern was observed. The friction factor in the baffled vessel using the MAXBLEND impeller had large-scale fluctuations upon installing baffle clearance, which may show the enhancement of heat/mass transfer at the sidewall of the vessel.2022年01月, Industrial and Engineering Chemistry Research, 61(3) (3), 1514 - 1522研究論文（学術雑誌）
- Abstract: Latex paints are widely used, and many researchers pointed out that the film formation process depends on the deformability of dispersed polymer particles. However, the relationship between the film formation process and drying rate has not been totally understood due to the lack of accurate data on drying rate throughout the drying process. In the present study, we measured the drying rate of latex coating by the temperature change method proposed by Imakoma in convective drying. We revealed that the drying process significantly depends on particle deformability, especially in the former stage of the falling drying rate period. At a low drying temperature, the close-packed structure of polymer particles is formed throughout the film at the end of the constant drying rate period. On the other hand, partially deformed soft particles due to wet sintering inhibit the drying rate even under high moisture content at high drying temperatures. In either case, after forming the closest-packed structure, the shrinkage of the gap space between particles due to capillary deformation decreases the drying rate, proportional to the moisture content.

- Polystyrene particles were dispersed in glycerol solution containing sodium chloride. The orthokinetic agglomeration process of the particles was observed in a mixing tank agitated by a six-blade Rushton turbine. It is found that the median diameter of agglomerates was initially increased and asymptotically approached a constant value. Bimodal particle size distributions were obtained within all of the experimental conditions and the stable size of produced agglomerates was independent of the rotational speed of the impeller. On the other hand, the amount of produced agglomerates was increased as the increase in the rotational speed of the impeller. Considering the experimental results, the population balance equation of a mathematical model to describe the evolution of the agglomerates was simplified. Then a representative shear rate taking into account the shear history of individual particles was proposed and its applicability was evaluated. It is showed that this shear rate is useful to predict agglomeration behavior of particles and a conventional representative shear rate in a mixing tank is overestimation.2021年07月, Chemical Engineering Research and Design, 171, 73 - 79研究論文（学術雑誌）
- The role of hydrodynamic interaction between micron-sized particles on the motion of a single magnetic probe particle, on which an external magnetic force is exerted, is studied. The motion of a probe particle in an index-matched suspension of surrounding particles is investigated using an optical microscope and image analysis technique. When inter-surface distance is smaller than the diameter of probe particle, the velocity of probe particle is reduced but rarely affected by the size of surrounding particles. The reduction of probe particle velocity is well associated with Péclet number of surrounding particles, but the degree of the suppression becomes significant below the critical inter-surface distances. The hydrodynamic interaction becomes many-body problems under the condition, and as a result, the bulk viscosity becomes larger than that under complete dispersion.2021年05月, Journal of the Society of Powder Technology, Japan, 58(3) (3), 138 - 146研究論文（学術雑誌）

- © 2019 Elsevier Ltd and IIR The sedimentation and flow characteristics of micro-encapsulated phase change materials have been investigated. As a phase change material, trimethylolethane clathrate hydrate having 218 kJ kg−1 of latent heat was used and encapsulated in silica hard-shell microcapsules, which size distribution has two peak at 15 µm and 59 µm. A cationic surfactant, oleylbishydroxyethylmethylammonium chloride with a counter-ion, sodium salicylate was used as drag reducing additives and poly vinyl alcohol was used as a stabilizer. From the results, it was found that the combination additive prevents effectively the microcapsule sedimentation. The drag reduction was also observed to occur in the high Reynolds number region. Thus, the present additive was concluded to be promising for the latent heat transportation by use of silica hard-shell microcapsules containing phase change materials.2019年10月, International Journal of Refrigeration, 106, 18 - 23[査読有り]研究論文（学術雑誌）

- Ammonium alum hydrate is a promising material for a latent heat transportation system for higher temperature around 50 °C. However, there were two big problems to be solved. One is a low fluidity of the slurries due to increasing the viscosity the other is a sedimentation of phase changed ammonium alum hydrate particles in the slurry due to high density of the particle, which causes pipe blockage. In this study, in order to solve these problems, we added drag reducing surfactants and polyvinyl alcohol (PVA) to the ammonium alum hydrate solution, and investigated the effects of them. Particle growth and sedimentation of ammonium alum in the solution were prohibited by adding both surfactants and PVA. Addition of only PVA to ammonium alum solution didn't prevent the particle growth and the sedimentation. That is, the effect was a synergetic effect. In order to understand the synergetic effect, inner structures of a solution containing surfactants and PVA were measured by a dynamic light scattering (DLS). Flow and heat transfer characteristics were also measured and analyzed. Friction coefficients of solutions and slurries were decreased with the drag reducing surfactants, which was not affected by addition of PVA. Heat transfer characteristics of ammonium alum hydrate slurries were higher than that of solution with surfactants and PVA. All the results confirmed the applicability of the ammonium alum hydrate slurries for the high temperature latent heat transportation systems.Elsevier Ltd, 2018年09月, International Journal of Heat and Mass Transfer, 124, 1334 - 1346, 英語[査読有り]研究論文（学術雑誌）
- An experimental study was performed to investigate the relationship between the extensional rheological properties of polymer solutions and vortex deformation in turbulent flow. Polyethyleneoxide as a flexible polymer and hydroxypropyl cellulose as a rigid polymer are added to two-dimensional (2D) turbulent flow. Specifically, 2D flow is advantageous as it examines the effect of the extensional rheological properties of polymers on the flow. In the study, 2D turbulent flow and vortex shedding in 2D turbulent flow were observed using interference patterns and particle image velocimetry (PIV). Power spectrum of the 2D flow images and 2D turbulence statistics calculated by PIV analysis indicated that there are three flow regimes of vortex shedding in the 2D turbulent flow of the polymer solution. The vortex shedding in the 2D flow was categorized into three types, and this was affected by the relaxation time of the polymer solutions.Elsevier B.V., 2018年04月, Journal of Non-Newtonian Fluid Mechanics, 254, 1 - 11, 英語[査読有り]研究論文（学術雑誌）
- In order to clarify the mechanism of the bulge structure appearance observed in a cavity swept by a visco-elastic fluid, velocity fields were measured by a two-dimensional particle image velocimetry (PIV). The rib height, the cavity length, the flow path height and the flow path width were fixed at 20 mm, 100 mm, 40 mm and 75 mm, respectively. The Reynolds number was also fixed at 1,700 where the bulge structure appeared as reported by the previous study. The spanwise positions of the two-dimensional PIV were changed in 6 steps from the center plane to the outer region. From the results, it was found that the bulge structure has high-level fluctuation and its intermittency is related to the longest relaxation time. The bulge structure appears when the main flow separated from the upstream top corner of the cavity is intensified. The separated main flow contracted in the former cavity region expands not only toward the cavity bottom but also toward the outside walls of the flow path. In order to supply the fluid in the center plane, the backward flow occurs in the cavity. This flow motion was concluded to be a basic mechanism of the bulge structure appearance.Society of Rheology, 2018年, Nihon Reoroji Gakkaishi, 46(1) (1), 29 - 36, 英語[査読有り]研究論文（学術雑誌）
- Extensional flow properties of dilute viscoelastic solution have attracted much attention for almost three decades. This is because extensional viscosity or relaxation time of viscoelastic solution under extensional stresses add a lot of impact on fluidity of the solution the phenomenon is related to many industrial applications. Several techniques were proposed and many studies were conducted to measure extensional properties of polymer solutions. However, less studies were reported in the case of non-uniform solution, such as suspensions. In this study, we propose a relatively simple method to measure extensional viscosity. We adopt a syringe-shape abrupt contraction channels for the measurement the syringe-shape apparatus is useful to contain non-uniform dilute solutions. As a first step to develop the experimental apparatus and method, we tested polymer solutions. Polymers used to prepare sample solutions were polyethylene oxide (PEO), hydroxypropyl cellulose (HPC) and polyacrylic acid (PAA). Each polymer has different flexibility, which cause different characteristics of the extensional viscosity of polymer solutions. Extensional viscosities obtained in this study detected the characteristic of each polymer solution. Extensional viscosities of PEO solution was increased by increasing extensional rates that of HPC and PAA solution were decreased by increasing extensional rates the tendency was explained by relaxation times of each polymer solution.Society of Rheology, 2018年, Nihon Reoroji Gakkaishi, 46(1) (1), 13 - 22, 英語[査読有り]研究論文（学術雑誌）
- We previously reported that a rotationally reciprocating impeller, which slowly rotates back and forth with a sinusoidal change in the rotational speed, can realize superior mixing performance even under moderate fluid flow. In the case of crystallization process, it is expected that the rotationally reciprocating mixing suppresses crystal brakeage caused by collision to impeller plate and inhomogeneous supersaturation due to notable mixing performance. In the present study, we studied reactive crystallization process of salicylic acid and investigated the effect of mixing conditions on the size and shape of crystals. For a steady rotational mixing, the largest crystal size was obtained at the appropriate mixing condition, and the size and shape of crystals are both affected by the rotational speed. Meanwhile, it is found that the size of crystals maintained roughly constant in the wide range of mixing condition of the rotationally reciprocating mixing. Additionally, no significant difference in the shape was observed even at different reciprocating conditions.Society of Chemical Engineers, Japan, 2018年, Journal of Chemical Engineering of Japan, 51(2) (2), 159 - 165, 英語[査読有り]研究論文（学術雑誌）
- To investigate the sedimentation and flow characteristics of hard-shell microcapsule/water slurries, the apparent viscosity, apparent dispersion volume fractions, and friction characteristics were measured. The hard-shell microcapsule contains disodium hydrogen phosphate hydrate as a phase change material. Poly (vinyl alcohol) (PVA) with a concentration from 0 to 2,000 ppm was applied as a dispersant. A drag-reducing surfactant system was also added to the slurries to improve the flow characteristics of the slurries. As a drag-reducing surfactant, oleylbishydroxyethylmethylammonium chloride was added at 2,000 ppm with a counter-ion of sodium salicylate. As a trial, the concentration of microcapsules was set at a low value at 1 or 2 wt%. From the results, severe adsorption of surfactants onto the hard-shell microcapsules was found. Then, no drag reduction or sedimentation prevention occurred in the cases without PVA. However, there is a weak sedimentation prevention effect and effective drag reduction effect when PVA is present. Thus, it is concluded that the desorption of surfactants from the microcapsules occurs and forms a synergetic structure with the PVA.International Institute of Refrigeration, 2018年, Refrigeration Science and Technology, 2018-, 174 - 181, 英語[査読有り]研究論文（国際会議プロシーディングス）
- For effective use of excess exhaust heat from gas engines, a novel PCM was prepared by adding anhydrous sodium sulfate and D-mannitol to ammonia alum hydrate. It melted and stored latent heat at the temperature range of exhaust heat from gas engines (around 90°C). Heat storage and release characteristics of the novel PCM were investigated with a heat storage tank containing hot water and the novel PCM packaged into resin bags. As a result, the novel PCM stored and released more than 400 MJ×m-3 of heat at the temperature range between 80°C and 90°C. The amount of heat storage and release by the PCM was approximately ten times higher than that of water with same volume. This result indicates that the novel PCM can reduce the volume of hot water tank dramatically in addition to storing and releasing exhaust heat from gas engines.International Institute of Refrigeration, 2018年, Refrigeration Science and Technology, 2018-, 214 - 221, 英語[査読有り]研究論文（国際会議プロシーディングス）

- The fabrication method of silica hard shell microcapsules containing disodium hydrogen phosphate dodecahydrate (Na2HPO4 center dot 12H(2)O) has been developed. The effects of the mixing rates for the emulsification, of the volume ratios of solutions and of surfactant concentrations on the size of hollow microcapsules have been also studied. From the results, it was confirmed that silica hard shell microcapsules can contains Na2HPO4 center dot 12H(2)O with the present method using hollow microcapsules. The present micro-encapsulated Na2HPO4 center dot 12H(2)O was also found to cause the supercooling depression effect. As the fabricated microcapsules have no flammability, the present microcapsule was concluded to be a promising item not only for latent heat transportation media but also for the static thermal storage materials for architectural structures. From the studies on the fabrication parameters, it was concluded that the control of the surfactant concentration is effective for controlling the size of microcapsule. (c) 2017 Elsevier Ltd and IIR.

- The structural change during particle dispersion process of highly concentrated slurries of PMMA and graphite particles was investigated in terms of viscoelasticity. PMMA particles having weak interaction are easy to be dispersed, and a higher shear rate was preferable for stable dispersion. In contrast, aggregated graphite particles generate sedimentation layer. Therefore, non-uniform slurry was obtained at the lowest shear rate, while the formation of network of aggregated graphite particles resulted in a highly viscoelastic slurry when dispersing at higher shear rates. Additionally, it was considered that the particle dispersion is completed at the shear rate, when the loss moduli of slurry and dispersing medium showed the same frequency dependence.粉体工学会, 2016年06月, 粉体工学会誌, 53(6) (6), 371 - 379, 日本語[査読有り][招待有り]研究論文（学術雑誌）
- The present study deals with the flow field in the circular cross section of a cylindrical vessel induced by a rotationally reciprocating impeller, rotating back and forth with gradual change in rotational speed. A periodically stable velocity field was measured by PIV and also simulated by CFD. It was revealed that the velocity field near the liquid free surface is basically 2-dimensional, except for the acceleration period at Re = 43, and agrees well with 2-dimensional CFD simulation, except for the development process of 3-dimensional tip vortices at Re = 43. The separation behavior of the vortices originally generated at the impeller tip changed with increasing Reynolds number. No separation was observed at a lower Reynolds number, while the separated vortices turn into 3-dimensional potential vortices and remain as 2-dimensional vortices at the next impeller counterturn at higher Reynolds numbers. The fluctuation of each velocity component was remarkably small, suggesting that the flow field even at the highest Reynolds number was still laminar. It is found that effective transportation of energy from the impeller to 3-dimensional potential vortex is related to a large and constant power number, which is reported in our recent publication.SOC CHEMICAL ENG JAPAN, 2016年04月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 49(4) (4), 341 - 349, 英語[査読有り]研究論文（学術雑誌）

高濃度マイクロ粒子スラリーに対してナノ粒子を微量添加したときのレオロジー変化について研究した．マイクロシリカ粒子が凝集している場合，その凝集構造がレオロジーを支配し，ナノ粒子添加効果は見られない．これに対して，高分散マイクロシリカ粒子スラリーに対してアルミナナノ粒子を添加すると，マイクロ粒子間隙部をナノ粒子凝集体が閉塞し，スラリーはゲル化した．この現象は粒子濃度が高いほど顕著に見られ，50 vol%では僅か0.01 vol%のナノ粒子によってゲル化することを明らかにした．これに対して，シリカナノ粒子はマイクロシリカ粒子表面に吸着するので粘度増大効果は見られないが，高せん断域でナノ粒子が離脱しクラスターを形成すると，一時的に粘度が急増する断続的シアシックニング挙動を発現することを見出した．
- Effects of the Molar Ratio of Counter-Ions on Flow Characteristics of Surfactant Solutions Sweeping CavitiesAn experimental study has been performed in order to investigate the optimum rheological characteristics for a technique of heat transfer augmentation in a cavity between ribs mounted in parallel plates. The rheological characteristics of visco-elastic fluid were changed by controling the molar ratio of counter-ion to a cationic surfactant. Flow visualization experiments and pressure loss measurements were conducted in the range of solvent Reynolds number from 100 to 2,500 and in the range of molar ratio from 0.50 to 10. Under this condition, the zoro-shear Reynolds number and the Weissenberg number ranged from 2.01 to 120 and from 1.94 X 10(-2) to 9.15, respectively. From the results, flow penetration into the cavity occurred in the cases from 1.5 to 5.0 of molar ratio of counter-ions. However, the pressure loss became large in the cases when the remarkable Barns effect can be observed. On the other hand, the pressure loss became almost the same as that of water in the case when the molar ratio of counter-ions was set at 5.0. From this, it was concluded that the optimum fluid for the heat transfer augmentation in a cavity is required to have suitable elasticity and low viscosity as the molar ratio of counter-ions is set around 5.0.SOC RHEOLOGY, JAPAN, 2016年, NIHON REOROJI GAKKAISHI, 44(3) (3), 143 - 151, 英語[査読有り]研究論文（学術雑誌）
- In order to study the effects of extensional viscosities on turbulent drag reduction, experimental studies using two-dimensional turbulence have been made. Anisotropic structures and variations of energy transfer induced by polymers are considered. Polyethyleneoxide and hydroxypropyl cellulose having different flexibility are added to 2D turbulence. The different flexibility induces different characteristics of extensional viscosity. In addition, since increases of the extensional viscosity also depends on extensional rate, different extensional rate are added to the flow. Variations of the turbulence are visualized by interference patterns of 2D flow. The interference patterns are analyzed by 2D Fourier transform to detect effects of polymers in the streamwise and in the normal directions. Scaling exponent of power spectrum of the interference patterns indicate how energy transfer was changed by polymer additives. The energy transfer was also discussed by velocity field measured by PIV analysis. Wavelet transform are also applied to detect variations of characteristic scales in 2D turbulence.SPRINGER, 2016年01月, FLOW TURBULENCE AND COMBUSTION, 96(1) (1), 227 - 244, 英語[査読有り]研究論文（学術雑誌）
- Dispersion and Re-aggregation of Particles in a Suspension Flowing in an Abrupt Contraction ChannelA flow experiment of a dilute suspension and aggregation/dispersion analysis of fine particles in a non-uniform shear field were performed. We investigated the dispersion characteristics in a microchannel with an abrupt contraction section. The dispersed particles and dispersion media were polystyrene and aqueous glycerine, respectively. The particle diameter and solid volume fraction were 3.5 mu m and 0.001, respectively. Citric acid (0.5 and 1.0 wt%) was added as a non-ionic salt in order to investigate the effect of the aggregational force. The suspension was introduced into the microchannel with a syringe pump at a volume rate of 0.3 mu l-min(-1). The aggregation/dispersion characteristics of the fine particles were observed with a microscope and analyzed by image analysis. We observed the breakup and re-aggregational behavior of the fine particles in a dilute suspension. The cumulative frequencies of fine particles fluctuated through the channel. From the results, we posit the possibility that the non-uniformity of ions affect the aggregational characteristics of fine particles in a shear flow.SOC RHEOLOGY, JAPAN, 2016年, NIHON REOROJI GAKKAISHI, 44(3) (3), 153 - 158, 英語[査読有り]研究論文（学術雑誌）
- In order to investigate a fouling mechanism, adhesion behavior of a calcium carbonate particle onto various walls having different hydrophilic/hydrophobic characteristics have been studied. First, adhesion force was measured by atomic force microscope, which decreases with hydrophilicity of walls. Second, fouling phenomena on each plate was measured over time. In the case of the hydrophobic surface, bare copper plate, adhesive calcium carbonate crystal was increased, and the amounts reached the constant values. On the other hand, in the case of the hydrophilic surface, glass plate and hydrophilic coated copper, calcium carbonate crystal was adhered for several hours, then the crystal was removed from the plates. Crystal types of calcium carbonate on each plate were also analyzed by a X-ray diffractometer. The crystal type was varied due to the hydrophilic/hydrophobic characteristics of the plates. From the results, it was expected that the hydrophilic treatments to wall surfaces in heat exchanger might be useful to control fouling phenomena. (C) 2015 Elsevier Ltd.

- PARTICLE SEDIMENTATION DEPRESSION WITH STABILIZERS AND SURFACTANTS ON PHASE CHANGE MATERIALSThe effect of the size of a combination structure of poly(vinyl alcohol) (PVA) as a stabilizer and drag-reducing surfactants in water on the sedimentation of particles of phase change materials (PCMs) in solutions was investigated. Behenyl trimethyl ammonium chloride was used as a surfactant with a 1.5 molar ratio of sodium salicylate as a counter-ion supplier at a constant surfactant concentration of 2,000 ppm in water, while the concentration of PVA was varied from 0 to 2,000 ppm. The structural size of the combined PVA and surfactant was measured with a dynamic light scattering (DLS) system. DLS analysis indicated that a large structure is formed by the interaction between PVA and surfactants. In addition, this structure becomes larger with the PVA concentration, and the occupation volume of the structure expands widely in a fluid. Thus, it was concluded that this large structure formation could cause an effective reduction of particle sedimentation in latent heat systems.INT INST REFRIGERATION, 2016年, 11TH IIR CONFERENCE ON PHASE CHANGE MATERIALS AND SLURRIES FOR REFRIGERATION AND AIR CONDITIONING, 152 - 161, 英語[査読有り]研究論文（国際会議プロシーディングス）
- FABRICATION CHARACTERISTICS OF PHASE-CHANGE MATERIALS OF SILICA HARD-SHELL MICROCAPSULESA novel fabrication technique of hard-shell microcapsules (HSMC) containing trimethylolethane hydrate as a phase change material has been tested with a double nozzle method. The inner and the outer diameters of the inner nozzle and the inner diameter of the outer nozzle of the double nozzle were fixed at 0.24, 0.46 and 0.8 mm, respectively. The inner/outer flow ratio was changed from 2.50 to 5.00, while the flow rate injected from the outer nozzle was kept constant at 2 ml/h. From the results, it was found that the mean diameter of capsules is 1.58 mm when the flow rate ratio is 2.50. In this case, a reasonable latent heat was also obtained. Thus, it was concluded that the present method for the fabrication of the capsules containing the trimethylolethane hydrate can be a promising method.INT INST REFRIGERATION, 2016年, 11TH IIR CONFERENCE ON PHASE CHANGE MATERIALS AND SLURRIES FOR REFRIGERATION AND AIR CONDITIONING, 246 - 253, 英語[査読有り]研究論文（国際会議プロシーディングス）

- A large plate impeller was rotated back and forth in a cylindrical vessel. Simultaneous and continuous measurements of the rotational torque on the mixing shaft and impeller angular position were carried out. The power consumption was computed by integrating the product of the measured torque and impeller rotational speed. The relationship between the power number and Reynolds number revealed that the Reynolds number became small for the transition in power characteristics and that the constant power number became large for the larger Reynolds number region at a small reciprocating amplitude with a large impeller acceleration. This is because a more remarkable startup flow was frequently repeated. The larger power number suggests that the rotationally reciprocating impeller has more efficient power characteristics compared to common rotational impellers. In terms of the torque variation, the measured torque was mainly dominated by the viscous force in the smaller Reynolds number region. As the Reynolds number increased, the phase lag between the torque and impeller speed increased even in the smaller Reynolds number region, and the measured torque was observed to fluctuate in the transition region. Although the measured torque was mainly dominated by the inertia force, the phase lag and magnitude of fluctuation did not increase any further at large Reynolds numbers.SOC CHEMICAL ENG JAPAN, 2015年11月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 48(11) (11), 885 - 890, 英語[査読有り]研究論文（学術雑誌）

- Inertio-elastic instability characteristics of visco-elastic fluids sweeping a micro-cavity mounted in a micro-duct have been investigated in order to develop a effective micro mixer. The cavity depth, the cavity length and the width of the wider flow path were fixed at 200, 1,000 and 400 μm, respectively while the solvent Reynolds number was changed from 0.100 to 100. As a visco-elastic fluid, a cationic surfactant/counter-ion system was applied. The molar ratio of counter-ion to surfactant was changed from 1.5 to 10 in order to control rheological characteristics of the fluid. Flow visualization experiments were performed with a high-speed camera mounted on a microscope. From the results, it was that a tonguing motion of the separation fluid bubble tip formed in the downstream region in the cavity occurs at a certain Weissenberg number larger than 200 due to the inertio-elastic instability. The fluctuating bulge structure was also observed on the upstream side wall of the cavity in a higher range of the Weissenberg number. These characteristics were considered to be effective for a mixing process. It was also found that the separation bubble size is determined with Weissenberg number for all fluids treated in this study, but the previous correlation suggested for a macro-scale system does not agree with the present results. This indicated that some different relaxation structure exists in a micro-scale system.The Japan Society of Mechanical Engineers, 2015年02月, 日本機械学会論文集, 81(823) (823), 14 - 00650, 日本語[査読有り]研究論文（学術雑誌）
- Cemented carbide is usually produced by sintering particles of metal carbides with binders. The non-aqueous suspension of both materials is spray-dried to produce granules having uniform material distribution, resulting in the excellent toughness of final products after sintering. Although the status of particle aggregation in a suspension should have a strong relationship with granule properties, the effect of surfactant on aggregative nature of particles has not been systematically investigated. In the present study, a new instrument was developed to measure apparent viscosity of metal particle suspension without sedimentation in order to investigate particle aggregation from the theological point of view. Additionally, the particle interaction has been quantitatively evaluated based on Usui's thixotropy model. It is found that the particle interaction was gradually reduced as increasing surfactant concentration, whereas granule properties changed only at higher concentrations. We also found the suspension stability and product functionality are balanced at the critical concentration. (C) 2014 Elsevier B.V.

- The fabrication of silica hard shell microcapsules containing disodium hydrogen phosphate dodecahydrate has been developed. The effects of the mixing rate and time to emulsification of solutions added by a homogenizer, volume ratio of solutions and of surfactant concentration on the size of porous hollow microcapsule have been studied. From the results, it was found that the effect of mixing conditions and of the volume ratio is rather small compared with that of surfactant concentration in the present range. Thus, it was concluded that the control of the surfactant concentration is effective for controlling the size of microcapsule. It was also found that the containing ratio of disodium hydrogen phosphate dodecahydrate is smaller than the void fraction of microcapsules. This was considered partially due to the microcapsule agglomeration and partially to hydrogen desorption through the shell during of the reaction. The supercooling depression in the microcapsules was also found in this study. Thus, the present microcapsule was concluded to be a promising item not only as latent heat transportation media but also as static thermal storage materials.International Institute of Refrigeration, 2015年, Refrigeration Science and Technology, 2144 - 2154, 英語研究論文（国際会議プロシーディングス）

- We have investigated the drying process of latex dispersion coating from the perspective of particle packing process. The behavior of particle aggregates in latex dispersions under shear flow was evaluated based on rheological measurement: particle aggregation under steady shear is related to apparent viscosities and time variation of elastic moduli shows reconstruction of aggregates. The effect of applied shear strain in coating on the thinning behavior of the latex dispersion coatings has been investigated. We found that the packing fraction of particles at the end of a constant film thinning rate period or concentration intricately changed with applied shear strain and glass transition temperature, T-g, of latex particle. If particles are completely dispersed, deformable particles having lower T-g are packed up to a maximum packing density, showing a very short falling drying rate period. In the case of insufficient shear strain application, however, aggregates formed a loosely packed layer, resulting in the emergence of a clearly decreasing thinning rate period. In contrast, hard spheres having the highest T-g formed a loosely packing particle layer similar to aggregated lower T-g particles.SOC CHEMICAL ENG JAPAN, 2015年01月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 48(1) (1), 87 - 93, 英語[査読有り]研究論文（学術雑誌）
- Flow behaviors of sodium hyaluronate (HA-Na) in water solution and in phosphate buffered saline (PBS) solution as a viscoelastic fluids in planer abrupt contraction-expansion channels has been observed in this study. Especially, the effect of the geometry of the flow path on the flow behavior was focused on. The corner vortices in the corner of the upper region in the abrupt contraction-expansion channels were also analyzed to quantify the flow characteristics. The elasticity numbers of the solution, which is affected by rheological properties of the solution and the channel geometry had a big influence on the fluidity, that is, stable or unstable, when the concentration of the solution in lower. It was concluded that such stable and unstable flows are categorized on Wissenberg-Reynolds number space.American Society of Mechanical Engineers, 2015年, ASME/JSME/KSME 2015 Joint Fluids Engineering Conference, AJKFluids 2015, 2A, 7pages, 英語[査読有り]研究論文（国際会議プロシーディングス）
- Numerical Simulation of Particle Dispersion in Flow between Coaxial Cylinders under Unsteady Flow ConditionsTwo-dimensional numerical computations of unsteady flow of a suspension between two coaxial cylinders are performed. We investigate the dispersion characteristics based on a novel thixotropy model. The diameter of particles, solid volume fraction, and viscosity of dispersing media are set to 2.5 mu m, 0.15, and 195 Pa.s, respectively. The shear rate is suddenly changed from 0.1 s(-1) to 1 s(-1). For model validation, the numerical results are compared with previously reported experimental results. The mean number of particles in a cluster increases slightly shortly after the shear rate change, reaches a maximum, and subsequently decreases, finally attaining a steady state at 40 s after the shear rate change. Our model better expresses the time variation of the dispersion characteristics than the previous model. After the validation, the effect of bonding energy on the time-variation characteristics is investigated. The bonding energy is varied as 2.7 x 10(-13), 2.7 x 10(-12), and 2.7x10(-11) J. We observe that the asymptotic values of the mean number of particles in a cluster depend on the bonding energy, but this relationship is not linear. From our results, we posit the existence of a certain critical bonding energy with regard to the dispersion characteristics.SOC RHEOLOGY, JAPAN, 2015年, NIHON REOROJI GAKKAISHI, 43(3-4) (3-4), 85 - 92, 英語[査読有り]研究論文（学術雑誌）

- An experimental study has been performed to investigate the relationship between the extensional viscosity of polymers and the turbulent drag reduction. Self-standing flowing soap film was used to generate two-dimensional (2-D) turbulent flow to eliminate shear stress. Two types of polymers having different flexibilities were added to the 2-D turbulence. The effects of these polymers were visualized by the interference pattern of flowing soap films. The vortex deformation by adding polymers was analyzed by Fourier transformation and wavelet transformation. The scaling exponents of the power spectrum of interference patterns indicate that the mechanism of turbulence laminarization due to the extensional viscosity is anisotropic. A wavelet analysis reveals the high and low fluctuations of the polymer-added flow. Results from wavelet analysis indicate disappearing of original vortices, and appearing of new structures in low frequency in 2-D flow.

- This study deals with fluid mixing process in the circular cross-section of a cylindrical vessel using a rotationally reciprocating (back and forth rotation) plate impeller from the view point of experimental visualization and numerical simulation. We have investigated the fluid deformation process with the visualization of streak lines. It has been found that a pair of vortices generated at the impeller tip plays a crucial role in stretching and folding of streak lines. Additionally, for effective overall mixing, we found that fluid needs to be dragged inward to the region near the mixing shaft, stretched and folded along the impeller plate, and then extensively deformed from the impeller tip. However, since the path of fluid inward motion is rarely disturbed by locally strong vortices generated at the conditions of small amplitude and short period, a poor mixing region expanded from the mixing shaft to the vessel wall, which made two separated mixing regions in a vessel. With increasing amplitude, the poor mixing region shrunk near the mixing shaft. In the case of the largest amplitude and longest period, fluid was effectively deformed everywhere in the vessel, which leads to a highly intensified mixing process.SOC CHEMICAL ENG JAPAN, 2014年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 47(2) (2), 151 - 158, 英語研究論文（学術雑誌）

- The characteristics of oxygen dissolution accelerated by the use of micro-bubbles in a viscoelastic fluid were studied. An aqueous solution of a combination of a cationic surfactant and of a counter-ion supplier was used as a viscoelastic fluid. Flow visualizations and measurements on the time variation of the oxygen concentration were performed. From the results, it was found that the dissolution of oxygen rapidly occurs by the use of microbubbles, but the dissolution becomes slow in a highly elastic fluid. The flow observation of bubbles in a highly elastic fluid showed a chaining effect with bubble ascension. Bubble chaining was found to accelerate the agglomeration of bubbles and decrease the apparent gas-liquid interface area. Thus, such a chaining effect was concluded to disturb the dissolution of oxygen.SOC CHEMICAL ENG JAPAN, 2014年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 47(2) (2), 201 - 206, 英語[査読有り]研究論文（学術雑誌）
- Crystal Growth and Viscosity Behaviors of Ammonium Alum Hydrate Solution with PVA in Shear FlowAluminum ammonium sulfate dodecahydrate (ammonium alum hydrate) slurry is a promising latent heat medium for high-temperature systems. However, there exist the significant issues with this medium at high temperature with respect to crystal agglomeration, growth, and sedimentation. Therefore, the effects of adding drag-reducing surfactants and poly vinyl alcohol (PVA) on the formation process of ammonium alum hydrates crystals under a controlled shear flow have been investigated in this study. In addition, in order to investigate the impact of the surface hydrophilicity and hydrophobicity of cooling walls on the crystal growth, a copper plate and a silica coated copper plate were used as the substrates of the wall. From the results, it was found that the mean crystal size of the ammonium alum hydrate decreased with increasing shear rates and with the addition of surfactants and PVA. In addition, the crystals on the silica coated copper plate were smaller than those on the copper plate without a coating. Thus, the addition of drag-reducing surfactants and PVA and use of a hydrophilic surface prevented the crystal agglomeration and crysal growth of the ammonium alum hydrate under a shear flow. Furthermore, the viscosity of each solution was also measured, as affected by the various additives and by crystal agglomeration and growth.SOC RHEOLOGY, JAPAN, 2014年, NIHON REOROJI GAKKAISHI, 42(4) (4), 219 - 226, 英語[査読有り]研究論文（学術雑誌）

- In order to study a bulge structure observed in a cavity swept by a viscoelastic fluid, flow visualization experiments have been performed. The cavity depth, the cavity length and the width of flow path were fixed while the water Reynolds number based on the narrow flow path was changed from 680 to 4,200. From the results, the bulge structure formed on the upstream backward-facing side wall of the cavity in the mid-range of the Reynolds number was found to lead a fresh fluid into a cavity and to sweep the fluid near the cavity bottom wall. The bulge structure fluctuates very slowly and this fluctuation induces a tonguing motion of the tip of the separation bubble formed in the downstream region of the cavity. Thus, this structure can be expected to enhance the heat transfer from the cavity bottom.IOP PUBLISHING LTD, 2014年, XXI FLUID MECHANICS CONFERENCE, 530, 01255 - 01262, 英語[査読有り]研究論文（国際会議プロシーディングス）

- An experimental study has been performed to investigate the relationship between the extensional viscosity of polymers and the turbulent drag reduction. In order to obtain the flow which is mostly dominated by extensional flow, two-dimensional (2D) grid turbulence made by flowing soap films was used. Extensional rate added to the flow was controlled by changing the conformation of the grid. Polyethylene oxide, as a flexible polymer, and hydroxypropyl cellulose, as a rigid rod-like polymer were added to the flow. Several extensional rates affect polymer behaviors, which induce different effects. Drag reduction effects of polymers under several extensional rates were visualized and analyzed by image processing. Rheological properties of the polymer solutions were also measured by a rheometer. The results indicated that the mechanisms of energy transfer are different in the streamwise and normal directions. The critical concentration to observe drag reduction effects in 2D turbulence was changed by the extensional rate. When extensional rate is higher, the effects were started to observe from lower concentration. These results were confirmed to correspond to the drag reduction effects obtained by classical pressure drop experiments in a pipe flow.SPRINGER, 2013年11月, RHEOLOGICA ACTA, 52(10-12) (10-12), 949 - 961, 英語[査読有り]研究論文（学術雑誌）

- A model estimating local particle dispersion/aggregation behaviors in a suspension has been developed for a nonuniform shear flow. In this model, the size distributions of particle clusters were calculated with taking a balance of Brownian and shear coagulationsand shear breakup. A numerical simulation was performed for a two-dimensional backward-step flow as a non-uniform shear flow. A flow experiment using a micro-channel with a rib was also conducted for the verification of the present numerical analysis. The solid volume fraction of the suspension was set at 0.01 and the step height Reynolds number was keptconstant at 1.5×10-4 both for numerical and for experimental studies. The numerical results obtained in this study were rather reasonable compared with the experimental data. From this, it was found that the present numerical model is promising for estimating particle dispersion/aggregation in a non-uniform shear flow. © 2013 The Society of Rheology, Japan.2013年, Nihon Reoroji Gakkaishi, 41(2) (2), 75 - 81, 英語[査読有り]研究論文（学術雑誌）

- In this paper, aggregation/dispersion behaviors of particle clusters in a non-uniform shear flow have been numerically analyzed using a thixotropy model for estimating local cluster size distributions. The effects of the viscosity of the dispersion media, the solid volume fraction and the Reynolds number on the cluster size distribution in a two-dimensional flow between parallel plates were investigated in order to find the primary factor determining the cluster size distributions. The viscosity of the dispersed media, the solid fraction and the Reynolds number were changed from 195 to 1950 Pa.s, from 0.10 to 0.25 and from 0.1 to 1.0, respectively. From the results, it is found for each case that large clusters are observed at the central area of the channel, but it becomes smaller near the wall where high shear is added. The cluster size near the wall is dominated by the shear stress. On the other hand, it is found that the cross-sectional averaged cluster size depends on the bulk velocity under the present conditions. As the cluster size near the wall can be correlated rather well with the bulk velocity, it is concluded that the bulk velocity is a convenient and useful factor for the dispersion/aggregation behaviors of fine particles under the present conditions.SOC CHEMICAL ENG JAPAN, 2013年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 46(8) (8), 524 - 529, 英語[査読有り]研究論文（学術雑誌）
- Flow and heat transfer characteristics of ammonium alum hydrate slurries have been investigated. Ammonium alum hydrate has high latent heat of 251 kJ kg(-1) and its melting temperature is 51 degrees C when the concentration of ammonium alum in water was set at 35 wt %. The friction and the melting heat transfer coefficients were measured in a pipe flow with 13 mm of diameter. From the results, it was found that the friction coefficient of ammonium alum hydrate slurry shows almost the same value as that of water. On the other hand, the slurry shows higher heat transfer than that of water. Especially, the heat transfer enhanced rate becomes high when the temperature difference between the slurry and the heating flow was set small. This is because of the temperature sustainability of phase change material slurries. From this, it was concluded that ammonium alum hydrate slurry can be a promising candidate for a heating system.

- In order to develop turbulent drag-reducing technology by using an environmentally friendly additive in a water-transporting system, the drag reducing characteristics in a non-ionic surfactant (Oleyldimethylamineoxide, ODMAO) dilute aqueous solution flowing in a circular pipe of 5 mm diameter have been experimentally investigated with an air-driven fluid resistance test device. The rheological characteristics of the solution have also been examined by a rheometer with a cone-plate flow cell. The results show that the ODMAO solutions are drag-reducing when concentration is 400 ppm or higher, that the critical Reynolds number corresponding to the maximum drag reduction rate increases with both concentration and temperature, and that the maximum drag reduction rate can reach up to 70% in the straight pipe. At low shear rates, the shear viscosity of ODMAO solutions with a relatively high drag-reduction behaves similarly to Newtonian fluids; at above a certain critical shear rate, it is firstly shear-thickening, then shear-thinning. Such shear-rate-dependent characteristics of the shear viscosity are attributed to the different transitions of micellar network structure induced by different shear rates. Relaxation of shear stress after removing an applied constant shear rate at which the solution is in the SIS (shear-induced structure) state is found to be well expressed by a 2-step Maxwell model with a tail relaxation time much shorter than that for a drag-reducing cationic surfactant, which indicates that for the ODMAO solution, a viscoelasticity as strong as a drag-reducing cationic surfactant is not needed to realize turbulent drag-reduction.SCIENCE PRESS, 2012年03月, SCIENCE CHINA-TECHNOLOGICAL SCIENCES, 55(3) (3), 772 - 778, 英語[査読有り]研究論文（学術雑誌）
- 剪断速度増加に伴うポリスチレン粒子の凝集・分散挙動に対するカルボキシメチルセルロースの影響Dispersion and agglomeration of particles with a drastic change in fluid flow differs from those under a steady shear flow. In this study, the development and destruction of particle agglomerates with step-wise shear rate change were investigated by microscopic observation, and the results were compared with particle dispersibility predicted from rheological data. Polystyrene particles with strong agglomerative properties could be controlled by addition of small amount of carboxymethylcellulose (CMC). Once the particles were sufficiently dispersed, the agglomeration process was dominated by the collision of particles and was not affected by polymer concentration. When the amount of adsorbed CMC was sufficient to prevent the aggregation of particles, agglomerates readily dispersed to an agglomerative state corresponding to the applied shear rate. However, insufficient adsorption of CMC resulted in a heterogeneous agglomeration process that took longer time to attain steady agglomerated state. Slurry viscosity was employed to evaluate agglomerative nature except under conditions of complete dispersion.SOC CHEMICAL ENG JAPAN, 2012年, 化学工学論文集, 38(1) (1), 13 - 18, 日本語[査読有り]研究論文（学術雑誌）
- Onion-Like Structure of Viscoelastic Surfactant Solution Flow Induced by 4-Blade Paddle Impeller in a VesselAqueous solutions of some kinds of surfactants and counterions are known as viscoelastic fluids. The rheological properties and fluidity of the solutions are significantly affected by the surfactant and counterion concentrations. Thus, the solution is a potential solvent for industrial applications because a drastic change in the fluidity can be realized only through the addition of counterions. In this study, we focused on the characteristics of the fluid flow of viscoelastic surfactant solutions in a mixing vessel. It was found that in the vicinity of the impeller the fluid was actively mixed and contained a large number of laminated fluid lumps, forming onion-like structure. When the elastic force becomes comparable to the viscous force, the micellar network of the surfactant was deformed. Additionally, if the elastic force was not much smaller than the inertia force, the impeller region was covered by a network-deformed fluid and an onion-like structure was then formed. Moreover, a stable onion-like structure was obtained when the impeller rotated as slowly as possible or when the elastic force of the solution was more significant than the viscous one.SOC CHEMICAL ENG JAPAN, 2012年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 45(2) (2), 94 - 101, 英語[査読有り]研究論文（学術雑誌）
- Flow and Heat Transfer Characteristics of Ammonium Alum Hydrate Slurry Treated with SurfactantsThe flow and heat transfer characteristics of an ammonium alum hydrate slurry treated with drag-reducing surfactants have been investigated experimentally. Ammonium alum hydrate has a high latent heat of 251 kJ/kg, and its fusion temperature is 51 degrees C when the concentration of ammonium alum in water is 35 wt%. The friction coefficient and the heat transfer coefficient for melting were measured from a pipe flow with a diameter of 13 mm. From the results, it was found that the ammonium alum hydrate slurry treated with surfactants shows the effective drag reduction in a pipe flow. It was also found that the heat transfer of the slurry with the surfactants is reduced slightly; in particular, this was true in the case of a high temperature difference between the slurry and heating water flowing outside a test tube. However, the heat transfer coefficient of the slurry with surfactants divided by pressure loss was very high, and particle growth due to particle agglomeration could be reduced by the surfactants. From this, it was concluded that the ammonia alum hydrate slurry with the surfactant is a promising system as a heat transportation medium.SOC CHEMICAL ENG JAPAN, 2012年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 45(2) (2), 136 - 141, 英語[査読有り]研究論文（学術雑誌）
- Relaxation Behavior of a Drag-Reducing Cationic Surfactant SolutionExperimental study on the relaxation behavior of the drag-reducing surfactant solution has been performed in order to investigate the mechanism of the drag reduction occurrence. The relaxation times and the drag reduction rates were measured in a wide range of the surfactant concentration and of the molar ratio of the counter-ions to surfactants. From the results, it was found that the present surfactant solution has at most three relaxation times in a middle range of the surfactant concentration and of the molar ratio. It was also found that the drag reduction occurs when the shortest relaxation time of 0.1 s exists. Thus, it was concluded that the existence of the shear-induced structure having this shortest relaxation time is important for the drag reduction occurrence.SOC RHEOLOGY, JAPAN, 2012年, NIHON REOROJI GAKKAISHI, 40(2) (2), 85 - 90, 英語[査読有り]研究論文（学術雑誌）
- Study of drag-reducing mechanism of nonionic surfactant in a water flowTo explore the mechanism of turbulent drag-reduction by adding non-ionic surfactants additives into a water flow, the shear viscosity, shear stress relaxation, and flow birefringence effects were experimentally investigated by a cone-plate rheometer and a birefringence device, after experimentally identified the turbulent drag-reducing for APG (Alkyl Polyglucoside) solution in a circle pipe flow. APG solution showing to be drag-reducing up to 70%, has Newtonian shear viscosities at smaller shear-rates, non-Newtonian shear viscosities at larger shear rates, and it also shows SIS (Shear-Induced Structure) at a critical shear rate. The shear stress relaxation behavior is identical to that for water, which implies that APG solution is drag-reducing, but shows SIS rheological characteristics without viscoelastics. The rod-like micelles proved from the birefringent effects, and higher extensional viscosity could be considered to be essential for the drag-reduction.2011年12月, Shiyan Liuti Lixue/Journal of Experiments in Fluid Mechanics, 25(6) (6), 54 - 65, 中国語研究論文（学術雑誌）
- Turbulent drag-reducing and rheological characteristics of alkyl polyglucoside solutionIn order to develop the drag-reducing technology in turbulent water-transporting flow by environmental friendly surfactant additives to water, experimental investigation was carried out on the drag-reducing behavior, shear viscosity, and relaxation characteristics of shear stres of nonionic surfactant alkyl polyglucoside solution in a pipe, by a flow-drag test device driven by compressed air and a cone plate rheometer. The results showed that alkyl polyglucoside presents excellent drag-reducing ability, and when temperature and concentration increase, the critical Reynolds number with maximal drag-reducing rate increases. The shear viscosities are Newtonian at smaller shear-rates, and suddenly jump up at some critical shear rate, which is called as SIS (Shear-Induced Structure). Development and relaxation behavior of Shear stress is the same with water, which showed that the immediate causal connections is absent between SIS and viscoelastic effects.2011年11月, Sichuan Daxue Xuebao (Gongcheng Kexue Ban)/Journal of Sichuan University (Engineering Science Edition), 43(6) (6), 53 - 57, 中国語研究論文（学術雑誌）

- An understanding of the conversion process from slurry to particle layer on a substrate is required for the precise control of the particle alignment and the material distribution in the coated slurry. In this work, variation of coated slurry thickness during drying was applied to evaluate drying and particle layer formation simultaneously. The slurry used consisted of micron-sized silica or poly (methyl methacrylate) particles and an aqueous solution of poly-vinyl alcohol (PVA) possessing differing degrees of hydrolysis. During the drying process, initially the thickness of the coated slurry was observed to decrease at a constant rate in the concentration stage, and subsequently it began to show large fluctuations due to the emergence of particles on the drying surface in the packing stage. In the final fixing stage, the fluctuation of film thickness was restricted because particles were immobilized by highly viscous concentrated PVA or by PVA molecule bridging. Based on the variation and fluctuation of film thickness, we introduced two characteristic dimensionless time ratios: (a) void fraction in a packed particle layer at the end of concentration stage; and (b) the time required to fix particle position after the end of the packing stage. We concluded that the dispersed state and settling velocity of the particle determines the space between particles in a loose packing layer, and we found that the distribution of polymers in a particle layer has a strong influence on the mobility of particles in a tightly packed layer.TAYLOR & FRANCIS INC, 2011年, DRYING TECHNOLOGY, 29(9) (9), 1037 - 1045, 英語[査読有り]研究論文（学術雑誌）
- An experimental study on flow characteristics of trimethylolethane (TME) hydrate slurries treated with drag-reducing surfactants has been performed in order to investigate the effect of molar ratio of counter-ions to surfactants. As drag-reducing surfactants, oleylbishydroxyethylmethylammonium chloride was used. The molar ratio of counter-ions of sodium salicylate to surfactants ranged from 0 to 100 and surfactant concentration was changed in two steps; 1000 ppm and 2.000 ppm while the concentration of TME in water was set constant at 25 wt%. From the results, it was found that the drag reduction limitation becomes larger when the molar ratio of the counter-ions to surfactants is set around 20 for each surfactant concentration. From the detailed discussions, the drag reduction characteristics in a higher range of the molar ratio of counter-ions to surfactants were found to relate to the molar ratio of counter-ions to TME more significantly. Under the present conditions, it was concluded that 0.05 of the molar ratio of counter-ions to TME shows the most effective drag reduction. (C) 2010 Elsevier Ltd and IIR.

In the present study, the effect of the cavity number in the domain and of Reynolds number was focused on when the geometric parameters were set constant. From the results, it is found that the flow penetration into the cavities effectively causes the heat transfer augmentation in the cavities in any cavity region compared with that of water case. It is also found that the development of thermal field in cases of the present visco-elastic fluid is quicker compared with that of water cases. The present heat transfer augmentation technique using Barus effect of a visco-elastic fluid is effective in the range of low Reynolds number.AMER SOC MECHANICAL ENGINEERS, 2010年, PROCEEDINGS OF THE ASME INTERNATIONAL HEAT TRANSFER CONFERENCE - 2010, VOL 2, 635 - 641, 英語[査読有り]研究論文（国際会議プロシーディングス）
- Drying of Coated Slurry in Vapor of Drying SolventVarious thin films are produced by coating and drying of slurries. Cracks and fractures in the film, which frequently are encountered under a large drying rate condition, can be avoided by a reduction in drying rate. In this work, we propose a novel drying technique (pressure controlled drying), where the coated slurry is dried in a container filled with vapor of the drying solvent. If the inner pressure of the container is held reasonably higher than the saturation vapor pressure of the solvent, the drying rate can be successfully depressed. It was also turned out that the residual amount of the solvent in the coated slurry before and after holding the pressure has to be carefully controlled in order to work this drying technique effectively. The residual solvent is affected mainly not only by the time of holding the pressure but also by the container volume, decompressing capacity, and co-drying solvent. When the drying rate could be suppressed till the end of the constant drying rate period, the resultant film had a tightly packed cellular pattern and a smooth surface. This is probably due to the enhancement of particle arrangement with sufficient amount of the solvent and long drying time.SOC CHEMICAL ENG JAPAN, 2010年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 43(10) (10), 892 - 900, 英語[査読有り]研究論文（学術雑誌）

- Effect of Molar Ratio of Counter-Ions to Cationic Surfactants Treating Trimethylolethane Hydrate SlurriesExperimental studies on flow characteristics and particle size distributions of trimethylolethane (TME) hydrate slurries treated with drag-reducing surfactants have been conducted to investigate the effect of the molar ratio of counter-ions to surfactants. Oleylbishydroxyethylmethylammonium chloride is used as the drag-reducing surfactants. The molar ratio of sodium salicylate supplying counter-ions to surfactants is adjusted from 0 to 100 while the concentrations of TME in water and of surfactants remains constant at 25 wt% and at 2000 ppm, respectively. Results unexpectedly indicate that the drag reduction is greatest when the molar ratio of the counter-ions to surfactants is 20 against the fact that the higher molar ratio shows the higher drag reduction in water case. This indicates that some interaction between the counter-ions and TME molecules occurs and that it disturbs the formation of rod-like micellar structures causing the drag reduction. Thus, a molar ratio of counter-ions to surfactants of 20 is concluded to be the optimum for the drag reduction although it has a detrimental effect on the particle size under the present experimental conditions used.SOC CHEMICAL ENG JAPAN, 2010年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 43(4) (4), 349 - 354, 英語[査読有り]研究論文（学術雑誌）
- Investigation of Thermal Properties of Na2HPO4 Hydrate Slurries for Evaluating Their Use as a Coolant in Absorption ChillersThe thermal characteristics of inorganic disodium hydrogen phosphate dodecahydrate (Na2HPO4 center dot 12H(2)O) slurries in a water/ethylene glycol mixture were investigated in an attempt to reduce the size of absorbers in absorption chillers. In order to find the optimal concentration of Na2HPO4 center dot 12H(2)O and the optimal weight ratio of ethylene glycol to the mixture for cooling the absorber, solubility, phase change temperature, and latent heat were measured. The obtained results indicated that the hydrate slurry has an appropriate phase change temperature and sufficient concentration at the working temperature of the absorber when the hydrate concentration and the weight ratio of ethylene glycol to the mixture are set to 50 wt% and 0.4, respectively. Under this condition, the particle characteristics of the slurries were also measured. The particle size was found to be rather small, and it increased gradually. Thus, inorganic Na2HPO4 center dot 12H(2)O can be used as a cooling medium of the absorber in an absorption chiller.SOC CHEMICAL ENG JAPAN, 2010年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 43(1) (1), 34 - 39, 英語[査読有り]研究論文（学術雑誌）
- Agglomeration of Hydrate Particles in Aqueous Surfactant Solution with Counter-IonSlurry containing hydrate particles as a phase-change material in the aqueous surfactant solution with counter-ion can be applied to construct a highly effective heat transport system by the combination of latent heat and drag-reducing effect. However, the efficiency of the system is influenced not only by thermal characteristics but also by the fluidity of the slurry, which is influenced by the size and concentration of the particles and the agglomerates. In this study, we first investigate the condition providing steady crystallized slurry. It has been found that crystallization attained steady state within 1 hour after the start of crystallization under a well-agitated condition. The viscosities and first normal stress differences of the steady crystallized slurry and saturated solution were measured to clarify the interaction between hydrate particle and micellar structure of surfactant. As a result, it turned out that the agglomeration of the hydrate particles was influenced by the size and strength of the micellar structure depends on the concentration of counter-ion. In particular, a slurry containing a large amount of counter-ion showed a drastic decrease in fluidity in a certain shear rate range probably due to agglomeration of entangled structures of surfactants.SOC CHEMICAL ENG JAPAN, 2010年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 43(1) (1), 23 - 28, 英語[査読有り]研究論文（学術雑誌）
- Particle Size Depression and Drag Reduction of Ice Slurry Treated with Combination Additives of Surfactants and Poly(vinyl alcohol)Ice growth depression and drag reduction of ice slurries treated with a combination additive of cetyl dimethyl betaine (surfactant) and poly(vinyl alcohol) (PVA) have been investigated. From the results, it is found that the particle size becomes smaller when treated by the present surfactants compared with the corresponding result of each concentration of PVA. Additionally, particle growth depression can be observed due to a cooperative effect of surfactants, even in the case when PVA concentration was reduced to 4 g/l from 8.7 g/l, which was required in the case without surfactants. The present combination additives also cause drag reduction phenomena on the solution. Thus, the combination of surfactants and of PVA could be a promising candidate as additives for improvement of ice slurry fluidity.SOC CHEMICAL ENG JAPAN, 2010年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 43(6) (6), 482 - 486, 英語[査読有り]研究論文（学術雑誌）
- Numerical Study on Non-Absorbable Gas Control Using an Immersed Plate and Extraction in Evaporator/Absorber of Absorption ChillerNumerical computations on vapor flow and non-absorbable gas diffusion in the evaporator/absorber are performed in order to research the extraction method of non-absorbable gas. Non-absorbable gas behavior was tried to control by using an immersed plate and an extraction. From the results, it was found that both the immersed plate and the extraction can prevent from the performance decrease of the absorber. Non-absorbable gas tended to stay in the low vapor velocity region, because non-absorbable gas is rolled up into the low velocity region. Non-absorbable gas diffused from the low velocity region, when the vapor velocity entirely becomes lower because of the absorber performance decreases. In order to extract non-absorbable gas effectively, the extraction vent should be mounted near the position where non-absorbable gas was concentrated.SOC CHEMICAL ENG JAPAN, 2010年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 43(7) (7), 561 - 568, 英語[査読有り]研究論文（学術雑誌）

- The catalyst slurry used to form the catalyst layer of a polymer electrolyte fuel cell (PEFC) must be mixed for a sufficiently long period for good and stable cell performance. However, the optimum mixing duration must be determined from the viewpoint of process design. We prepared slurries with various amounts of Nafion and examined the influence of the slurry mixing time on the viscosity of the slurry, the size of the pores and distribution of elements in the catalyst layer, and the cell voltage of the PEFC. We found that when the Nafion content is optimum, these properties change gradually and stabilize after a sufficiently long mixing time as the progression of the adsorption of Nafion to catalyst particles. However, when the Nafion is comparatively low, although the properties stabilize after sufficient mixing, the Nafion molecules are first dispersed and then localized around aggregates. This reduces cell performance when mixing excessively long. These differences in the structural and electrochemical behaviors could be predicted by measuring the variation in viscosity during the mixing process. (c) 2009 Elsevier B.V.

- Development of a Liquid Film Model for the Evaporator in an Absorption ChillerA heat transfer model of the evaporator in an absorption chiller was developed by modification of Nusselt's film theory. This liquid film model was found to agree with existing experimental correlations in the film Reynolds number region in which the tube is assumed to be fully wetted. Next, two-dimensional numerical computations of vapor flow in the evaporator/absorber were performed with boundary conditions of the evaporator and the absorber respectively derived from each liquid film model. The results showed that the velocity distribution around the evaporator and the velocity field between the evaporator and the absorber are different from those when the vapor evaporates uniformly on the surface of the cylinders in the evaporator.SOC CHEMICAL ENG JAPAN, 2009年09月, KAGAKU KOGAKU RONBUNSHU, 35(5) (5), 417 - 424, 日本語[査読有り]研究論文（学術雑誌）

- Drag reduction characteristics of trimethylolethane hydrate slurries treated with surfactants have been investigated. The effects of the surfactant concentration and hydrate fraction of the slurry on drag reduction behaviors were focused on in this paper. The friction coefficient in a pipe flow of hydrate slurries treated with surfactants and the relaxation time of trimethylolethane solution with surfactants were measured. From the results, it was found that the effective drag reduction appears in the cases of high surfactant concentration even in cases of high hydrate fraction. This behavior was supported by the viscosity shear-thickening occurrence reported in the previous study. However, the effective drag reduction disappears in the cases of low surfactant concentration in spite of the shear-thickening occurrence. On this discrepancy, the relaxation time of the solution was measured. It is found that the critical concentration determined from the relaxation time disappearance well corresponds to the limitation of effective drag reduction occurrence. (C) 2008 Elsevier Ltd and IIR.

- Upgraded brown coal water mixture (UBCWM) preparation by using an Indonesian upgraded coal produced by upgraded brown coal (UBC) process, was carried out to study the effect of dispersing and stabilizing additives on theological behavior of the UBCWM. Three kinds of anionic dispersing additives, naphthalene sulfonic formaldehyde condensate (NSF), poly (meth) acrylate (PMA) and poly styrene sulfonic acid (PSS) and three kinds of stabilizing additives, carboxyl methyl cellulose (CMC). rhansam gum (S-194) and gellan gum (S-60) were used in this study. Results indicate that the addition of NSF 0.3 wt.% together with S-194 0.01 wt.% is effective in preparing UBCWM with good slurryability and stability, based on its theological characteristics with the apparent viscosity at shear rate of 100 s(-1) and yield stress at zero point of shear rate. The theological behavior of all of the UBCWM that prepared, exhibits non-Newtonian Bingham plastic. From the economical point of view. the price of S-194 is expensive. Oil the other hand, CIVIC is cheap and abundant. Therefore, the addition of CMC 0.01 wt.% together with NSF 0.3 wt.% is also effective in preparing UBCWM with good fluidity and stability.

- In this paper, a model estimating the time-dependent distribution of cluster size consisting of fine particles in Newtonian molten polymer was proposed. The present model for agglomerative suspension was developed based on Usui's thixotropy model, derived by taking the balance between shear breakup, shear coagulation and Brownian coagulation processes. The analysis was applied to the experimental results for silica/(ethylene methyl-meta acrylate copolymer) suspensions. The time variations of cluster size distributions, of viscosities and of the mean numbers of particles in a cluster were calculated and the results were compared with experimental results for the cases of shear rates from 0.2 to 10 s(-1) when the solid volume fraction was set at 0.15. From the results, it was found that the present model can estimated the steady state values of the slurry viscosity and the mean particle numbers in a cluster as well as Usui's original model. However, the model could not sufficiently express the time variation of theological characteristics due to the over-estimation of the contribution of shear rate when the cluster size is small.

- Agglomeration Behavior of Particles in a Molten Polymer in a Steady Shear FlowThe behavior of the particle agglomerate in a polymer melt in dispersion and agglomeration processes was investigated. In the dispersion process of particle agglomerates, number of agglornerated particles and shear viscosity of the mixture were decreased in a similar manner, and the agglomerated number was well correlated by applied strain. On the other hand, in the agglomeration process of having reduced the shear rate applied, agglomerated number was increased after the increase in shear viscosity, when the mixture contained particles at a high Volume fraction. Such a delay will be caused by the interaction between polymer entanglement structure and agglornerated particles. The internal structure of the mixture of particle and polymer was discussed in the consideration of frequency dependency of tan delta. When applying shear at shear rate more than the frequency where tan delta showed the maximum, particle agglomerate was dispersed well, and the interaction between polymer and single particle mainly governs rheological behavior. In addition, if smaller shear rate was applied to the mixture after that, relaxation of entanglement structure will induce particle agglomeration.SOC RHEOLOGY, JAPAN, 2009年, NIHON REOROJI GAKKAISHI, 37(3) (3), 135 - 141, 日本語[査読有り]研究論文（学術雑誌）

- Improvement of Thixotropy Model Analyzing Dispersion Characteristics of Fine Particles in Newtonian Molten PolymerA model estimating the time-dependent distribution of cluster size consisting of fine particles in Newtonian molten polymer has been improved. The present model for agglomerative suspension was developed based on Usui's thixotropy model, derived by taking the balance between shear breakup, shear coagulation and Brownian coagulation process. The interparticle bonding energy in the model was assumed as a function of a cluster size in this study though it was assumed to be constant in the previous study. The analysis was applied to the experimental results for silica/(ethylene methyl-meta acrylate copolymer) suspensions. The time variation Of Cluster size distributions, of viscosities and of the mean number of particles in a cluster was calculated and the results were compared with experimental results mainly for the cases of the solid volume fractions from 0.10 to 0.25 when the shear rate was changed from 0.2 to 10 s(-1). From the results, it was found that the present model could estimate well the time dependency of cluster size distributions in a wide range of shear rate when the solid volume fraction was set at 0.15, and that the effect of the solid volume fraction was also sufficiently explained by the present model.SOC RHEOLOGY, JAPAN, 2009年, NIHON REOROJI GAKKAISHI, 37(4) (4), 191 - 198, 英語[査読有り]研究論文（学術雑誌）
- Effect of Shear Rate and Volume Fraction on Agglomerative Nature of Polymer LatexA model For predicting the latex agglomerate size during the coagulation process, when (lie growth and breakup of the latex agglomerates proceed simultaneously tit a turbulent now, is proposed in this paper. In this model, the size of the agglomerate was expressed as it function of the external shear force, the strength of the agglomerate, and file volatile fraction of the slurry. The strength of the latex agglomerate was determined by a measurement or the slurry rheology in accordance with Usai's approach, where an inter-particle flooding energy between primary particles was calculated front the viscosity data. With this model, it was possible to predict the absolute size of the cluster in file turbulent flow. To confirm the validity of this model, the latex was agglomerated in various agitation conditions in the stirring vessel, while file dependence on volume fraction was also examined. The relation between file experimentally determined latex agglomerate sizes and the calculated agglomerate sizes from file proposed model was evaluated.SOC CHEMICAL ENG JAPAN, 2009年, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 42(2) (2), 71 - 77, 英語[査読有り]研究論文（学術雑誌）

- スラリー塗膜の乾燥速度と表面の光学特性A slurry sample was prepared by dispersing spherical micro-particles of poly( methyl methacrylate) (PMMA) in aqueous solution of polyvinyl alcohol (PVA), and a coated film sample was prepared by applying the slurry sample on a polyester sheet. The drying rate of the film sample was measured by a modified temperature change method. The effect on the drying rate of micro-particle concentration, defined as micro-particle volume/dried polymer volume, was examined in the range from 0.25 to 1.0, in which the porosity of the dried film was expected to be zero, and the effect of the micro-particle radius was also examined. During the period of decreasing drying rate, the drying rate was found to decrease with increasing micro-particle concentration and with decreasing micro-particle radius. Subsequently, the drying rate was almost constant, and the porosity was almost zero. The constant drying rate observed during the latter period was explained by a mass transfer model incorporating drying stress proposed by the authors in this study. The gloss on the surface of dried film was also measured and found to decrease with increasing micro-particle concentration, but to be little affected by the particle radius.SOC CHEMICAL ENG JAPAN, 2009年, 化学工学論文集, 35(3) (3), 297 - 303, 日本語[査読有り]研究論文（学術雑誌）
- The Effect of Shear Rate on Heteroaggregation Behavior of Latex Polymers and Suspension Polymers in Aqueous MediaThe effect of shear rate on heteroaggregation behavior of latex polymers and suspension polymers in aqueous media was investigated. Heteroaggregation was carried out in a stirred vessel under various stirring rates and temperatures. Large suspension polymer particles were selectively coated by small latex polymer particles at specific stirring rates corresponding to each temperature. The heteroaggregation dynamics were analyzed from the cluster strength of the coating latex polymer layer and external shear force. The cluster strength of the latex polymer was determined by using Usui's rheology model, where the inter-particle bonding energy was derived from both the rheological data and the rate of energy dissipation per unit mass in the stirred vessel. In contrast, a relation between the diameter of the cluster of the latex polymer particles and apparent shear rate was derived from Kobayashi's theory, which is based on the theoretical treatment on the break-up of a droplet. By combining both theories, the heteroaggregation process was characterized by the cluster strength of the latex polymer layer against the external shear force. The homogeneous coating was only formed in a specific condition where the favorable balance between the external shear force and the cluster strength of the latex polymer layer was achieved.SOC CHEMICAL ENG JAPAN, 2008年09月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 41(9) (9), 845 - 854, 英語[査読有り]研究論文（学術雑誌）
- The characteristics of liposome formation in a micro-tube have been studied to develop a novel production method that forms the liposomes with a desired size homogeneously. In this method, the inner wall of the micro-tube was used to spread the liposomal lipid on. Then, instead of conventional rigorous agitation, an aqueous solution was fed through the tube, which peeled off the thin lipid layer formed liposomes. This resulted in a sharp peak in the size-distribution profile, and the size of liposomes was found to be dependent on the flow velocity anti on the micro-tube size. Moreover, the Yield of the liposomes of the desired size in our method was much higher than that in the conventional method, because our method produced liposomes uniform in size. From these findings, we concluded that the friction drag in the micro-tube is applicable for the efficient production of liposomes and a microfluidics device consisting of micro-tubes is a promising tool in the production of liposomal formulations.SOC CHEMICAL ENG JAPAN, 2008年08月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 41(8) (8), 739 - 743, 英語[査読有り]研究論文（学術雑誌）

- Mixing mechanism of a multi-holed static mixerThree-dimensional numerical computations have been performed in order to investigate the mixing mechanism of a multi-holed (composed of two pairs of 4- and 5-hole elements) static mixer for Newtonian fluid. The hole Reynolds number based on the size ofstraight part of the hole and the mean velocity in a hole of the 5-hole element, Rea, was changed in three steps from 5.25 to 52.7, while the hole size of the straight part of the bole, the pipe diameter and fluid viscosity and density were fixed at 5 mm, 18 mm, and 0.0978 Pa.s and 1304 kg.m(-3), respectively, which were the same as in the previous experiments. From the results, it was found that twin vortices are formed in a hole of the 5-hole element as observed experimentally in the previous study. These twin vortices cause the twist motion in a hole and intensify the mixing process of the static mixer. It was also found that the vorticity of the twin vortices linearly increases with the hole Reynolds number. Thus, the increase of the hole Reynolds number causes high mixing characteristics as pointed out in the previous study.SOC CHEMICAL ENG JAPAN, 2008年03月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 41(3) (3), 139 - 144, 英語[査読有り]研究論文（学術雑誌）

- Experimental studies on the relaxation characteristics of drag-reducing surfactants have been performed. The relaxation time after shear addition was measured by a cone-plate type rheometer in order to investigate the effect of the concentration of surfactants and counter-ions in the aqueous solution. The concentration of surfactants, oleylbishydroxyethylmethylanmonium chloride:Ethoquad 0/12, was changed from 1,000 to 4,000 ppm, while the molar ratio of counter ions, sodium salicylate, to surfactants ranged from 1.5 to 100. From the results, it was found that the relaxation behavior of surfactant solution causing drag reduction shows multi-mode relaxation with several relaxation times and that the larger relaxation time decreases with the molar ratio of counter-ions and by the concentration of surfactants. The number of relaxation times was also found to decrease with the molar ratio of the counter-ions and concentration of surfactants © 2008 American Institute of Physics.2008年, AIP Conference Proceedings, 1027, 860 - 862, 英語[査読有り]研究論文（国際会議プロシーディングス）
- The structure control of catalyst layer for polymer electrolyte fuel cell by the preparation condition of catalyst particle suspensionThe catalyst layer for PEFC is usually produced by the coating and drying of the catalyst particle suspension. In this study, we investigated the effect of the mixing process and the suspension composition on the structure of the catalyst layer. The structure had a reasonable correspondence with the suspension viscosity. Also, the transition of the viscosity is different among the compositions and enough long mixing time will not always result in an appropriate structure. When the fraction of polymer electrolyte to catalyst particle is small, the excessive mixing of the suspension decreased the volume of the void between catalyst particles and then deteriorated the performance.AMER INST PHYSICS, 2008年, XVTH INTERNATIONAL CONGRESS ON RHEOLOGY - THE SOCIETY OF RHEOLOGY 80TH ANNUAL MEETING, PTS 1 AND 2, 1027, 821 - +, 英語[査読有り]研究論文（国際会議プロシーディングス）
- The behavior of particle agglomerate in a Newtonian molten polymer in the dispersion and re-agglomeration processesTransition of the agglomerated state of particles in a molten polymer was investigated in dispersion and re-agglomeration processes. Moreover, the relationship between the number of agglomerated particles and shear viscosity was discussed. A steady shear was applied to the molten polymer containing spherical fine particles by using a cone plate type rheometer. Then, the number of agglomerated particles in a solidified polymer was evaluated. It was found that the dispersion behavior of agglomerated particles could well explain with strain, i.e. the deformation of a polymer. In the re-agglomeration process, the agglomerated number increased slowly compared with shear viscosity in case the shear rate in dispersion was large. It suggests that the inner structure of the polymer was maintained to a relatively high shear rate by coexistence of particles. When dispersed at further high shear rate, the agglomerated structure after the dispersion changed significantly and, as a results the re-agglomeration rate was drastically reduced.AMER INST PHYSICS, 2008年, XVTH INTERNATIONAL CONGRESS ON RHEOLOGY - THE SOCIETY OF RHEOLOGY 80TH ANNUAL MEETING, PTS 1 AND 2, 1027, 108 - 110, 英語[査読有り]研究論文（国際会議プロシーディングス）

- Comparative study of particle interaction between PMMA particles by Usui's thixotropy model and AFMThe inter-particle bonding energy between mono-modal spherical PMMA, particles with different particle sizes in aqueous media was evaluated by both Usui's thixotropy model and an atomic force microscope (AFM) measurement. Usui has recently proposed the thixotropy model in which the number of primary particles contained in an aggregated cluster was adopted as the thixotropic model parameter. This model was mainly developed for silica-water slurries which showed typical non-Newtonian and thixotropic characteristics. In this model, inter-particle bonding energy between primary particles is easily determined when the steady state viscosity data are given experimentally. On the other hand, the adhesive force between two particles was tried to measure directly by AFM in liquid recently. It is known that both the adhesive and repulsive forces between two particles were obtained through the force curve measurement. In this presentation, the inter-particle bonding energy was not only calculated by Usui's thixotropy model from the rheology data, but also it was directly measured by AFM, whereby we discuss its physical meaning. In addition, we describe the influence of the temperature and particle size on the inter-particle bonding energy between PMMA particles which is essential for understanding of the viscosity of polymer slurry.AMER INST PHYSICS, 2008年, XVTH INTERNATIONAL CONGRESS ON RHEOLOGY - THE SOCIETY OF RHEOLOGY 80TH ANNUAL MEETING, PTS 1 AND 2, 1027, 716 - +, 英語[査読有り]研究論文（国際会議プロシーディングス）

- The dispersing behavior of a particle agglomerate in a mixture consisting of spherical fine particles and a molten polymer was investigated with the application of shear in a cone-plate apparatus. After attaining a constant agglomerated state by applying a small shear, the shear rate was changed to a set value and kept constant over a certain time. Viscosity measurement during shear application and analysis of particle agglomeration in a solidified mixture were conducted. In a dispersing process, agglomerates were broken up to a steady dispersed state corresponding to the shear rate applied and the average number of agglomerated particles could be well correlated by a deformation of the mixture in each particle volume fraction. The viscosity of the mixture with a particle loading of 0.15 had a good relationship with the agglomerated number independent of shear rate; thus, the viscosity of suspension may help in the understanding of the dispersing behavior. However, the concentrated mixture could not achieve a complete dispersion and the viscosity was significantly affected by the time response of the agglomerated structure to shear application, although a dynamic rheological measurement of mixtures with different particle loadings provided much the same result.

- The effect of the swelling rate of latex particle on assembly morphology in seed coagulation by monomer dropletsThe swelling rate of latex polymer particles in seed coagulation was shown to be influential in determining the final morphology of the assembly of the latex particles. In the present work, droplets of various monomeric species were used as the coagulation seeds. The latex particles form assemblies by seed coagulation which starts on the surface of the monomer droplets. Assemblies with a dense shell formed when the latex particles swell with the monomer slowly enough to allow the latex particles to densely stack. The layer-by-layer immobilization of the latex particles proceeds without losing the spherical morphology of the individual assemblies. In this case, the final coagulation assembly is obtained as a spherically aggregated flock of the latex particles with a cavity in its center. On the other hand, the primary coagulation layer forms a monolithic hollow structure (shell) in the case where the latex particles on the monomer droplets entirely and rapidly swell before the second coagulation layer is completed. Subsequently, a sparse porous layer of the latex particles forms on the outer surface of primarily formed monolithic inner shell.SOC CHEMICAL ENG JAPAN, 2007年11月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 40(11) (11), 999 - 1006, 英語[査読有り]研究論文（学術雑誌）
- Optimization of preparation and drying conditions of titanium dioxide slurry for coating on a plastic substrateThe improvement of the strength and structure of a porous titanium dioxide (TiO2) thin film on a plastic film substrate as an electrode for dye-sensitized solar cells (DSCs) were investigated. Although a film type DSC is lightweight and flexible, it shows a poor binding to a substrate compared with a glass type DSC. By the use of the ordinary TiO2 slurry including a volatile solvent the thin film forms a lot of cracks during the drying process because of a rapid removal rate of the solvent and a strong interaction between TiO2 particles. In this study, we prepared well dispersed TiO2 slurry by using a planetary ball mill and it was condensed by centrifugal sedimentation. High concentration slurry is appropriate for the coating and drying because it has a small amount of solvent and good stability of liquid film after the coating. Further, the crack produced on the surface of the thin film could be reduced in a slow drying process by the control of the pressure and atmosphere. The TiO2 thin film, which was produced by the improved methods of slurry preparation and drying condition, showed good cohesiveness to a plastic film substrate.SOC CHEMICAL ENG JAPAN, 2007年11月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 40(11) (11), 973 - 979, 英語[査読有り]研究論文（学術雑誌）
- Effect of the composition and coating condition on the structure and performance of catalyst layer of PEFCThe structure of the catalyst layer of PEFCs has a considerable influence on the cell performance. The catalyst layer is manufactured by coating a suspension consisting of Pt/C catalyst particles and a Nafion solution. In a catalyst layer, the decrease in the Pt/C particle agglomeration controlled by the coating condition was reported to improve the performance; however, the influence that the coating condition exerts on the structure and then performance of the catalyst layer when the compositions of suspension are different has not yet been researched well. In this study, we researched a method to control the structure of a catalyst layer by the coating condition and suspension composition. The surface structure, which is well correlated with the predicted number of agglomerated Pt/C particles, showed good agreement with the performance. Under the condition where the Pt/C particles are not dispersed well, the performance was improved with an increase in the coating speed and Nafion content. However, that improvement became negligible at the optimum Nafion content providing maximal cell performance. Further, at a higher Nafion content, the excessive dispersion of Pt/C particles in the catalyst layer deteriorated the performance drastically. These results imply that the performance improvement by coating is effective when the suspension shows fairly high viscosity. Further, a little addition of solvent to decrease the viscosity also improves the performance; however it may be deteriorated by an excessive addition.SOC CHEMICAL ENG JAPAN, 2007年10月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 40(10) (10), 808 - 816, 英語[査読有り]研究論文（学術雑誌）
- Correlation of fluidity between solid-liquid and solid-gas suspensionsThe correlation of fluidity between solid-liquid and solid gas suspensions was examineed using the thixotropy model proposed by Usui et al., (2000a, 2000b, 2001) Shear-thinning behavior was observed for a solid-gas suspension of calcium carbonate particles. The decrease in apparent viscosity of the solid-gas suspension is attributed to the breakdown of agglomerative structure with the increase in shear rate. It was found that the predicted inter particle bonding energy for the solid-gas suspension corresponded well to that obtained for a solid-liquid suspension. The same tendency was reported previously for the case of silica suspension. Since the suspension viscosity is not greating sensitive the change in inter particle bonding energy, it may be possible to predict solid-gas suspension viscosity by predicting the inter particle bonding energy for a solid-liquid suspension, and by using the thixotropy model proposed by the present authors.SOC CHEMICAL ENG JAPAN, 2007年07月, KAGAKU KOGAKU RONBUNSHU, 33(4) (4), 315 - 318, 日本語[査読有り]研究論文（学術雑誌）

- 塗布乾燥における光学特性制御Three slurries containing particles of different sizes were coated onto PET film. The rotation rate of the spin coating, which is known to control the structure of spherical particle sols, was varied in the range of 1000-5000 min(-1). The coated films were then dried by conduction, radiation or convection. The appearance of the coated film was observed and haze was measured as an optical characteristic of the film. The appearance and haze of films coated with particles of 2 W or more in diameter were not affected by the drying method, but were affected by the rotation rate. On the other hand, those of films coated with 100 nm particle were strongly influenced by the drying method. Consequently, according to the size of the particle, by selecting the rotation rate or drying method, haze can be controlled.SOC CHEMICAL ENG JAPAN, 2007年01月, 化学工学論文集, 33(1) (1), 48 - 52, 日本語[査読有り]研究論文（学術雑誌）
- Design of particle handling processes requires the characteristics of powder on flowability. Although various indices exist, most were obtained from the static characteristics and cannot express the dynamic effect. In the case of liquid or gas, the characteristic of flowability is represented by viscosity. Especially in the case of liquid-solid suspension, it is well known that the viscosity changes by the degree of particle agglomeration, and the agglomeration of suspended particles is determined by "particle interaction". However, the characteristics of powder layer have not been well understood. In this study, a method to measure the viscosity of a gas-solid suspension was developed. FT4 powder rheometer was used to measure the torque exerting on the blade, which rotated and descended into a powder layer. These data were used to calculate the viscosity of powder layer. We concluded that the well-known powder index for flowability may represent its dynamic characteristics and that the powder viscosity may provide more detailed information on powder flowability.The Society of Powder Technology, Japan, 2007年01月, 粉体工学会誌, 44,1,4-9(1) (1), 4 - 9, 日本語[査読有り]研究論文（学術雑誌）
- Preparation of carbonized biomass water mixture and upgraded coal water mixtureBiomass is the third largest primary energy resource in the world after coal and oil. Due to its huge potential, the renewable and the corresponding positive role for CO2 reduction, the use of carbonized biomass for energy purpose is expected to increase. The carbonized biomass comes from agricultural waste and forest by-product. Carbonized plant and carbonized coconut cell biomass were mixed with water to study the possibilities of slurry preparation as a carbonized biomass water mixture (CBWM). Beside that, the upgraded coal by an upgraded brown coal (UBC) process was also studied to produce a UBC water mixture (UBCWM) with high coal concentration. The rheological characteristics of CBWM and UBCWM have been conducted by using a stress controlled rheometer. The results indicate that the maximum concentrations of the carbonized plant, carbonized coconut cell biomass, and UBC were 35.9, 51.2, and 61.5 wt%, when respectively using 0.3 wt% of naphthalene sulfonic acid (NSF), polymethacrylate (PMA), and NSF as dispersing additives, and 0.1 wt% of carboxyl methyl cellulose (CMC) as a stabilizing additive.SOC CHEMICAL ENG JAPAN, 2006年11月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 39(11) (11), 1206 - 1212, 英語[査読有り]研究論文（学術雑誌）

- Mixing characteristics of Newtonian fluid by a multi-holed static mixerThe mixing characteristics of a multi-holed static mixer have been studied for Newtonian fluid. A multi-holed static mixer composed of five pairs of 4- and 5-hole elements. The size of straight part of the hole, a, was changed in two steps of 2 mm and 5 mm and its inlet and outlet size, d, was also changed in two steps of 4 or 6 mm in the cases of a = 2 rum. The fluid viscosity and flow rate were also changed as parameters. Flow visualization experiments in a test pipe with 18 mm diameter were performed in order to observe the occupation ratio of dyed fluid, which is injected from the nozzle with 4 mm diameter mounted in the upstream of the static mixer. From the results, it is found that the Reynolds number based on the mean velocity in the 4 hole element and the hole size, Re-s, multiplied by a delivery ratio of the hole, d/a, well correlates the mixing and pressure loss characteristics. This is because there exist two mixing processes in the present static mixing system. One is the mixing process in a small hole by accelerated flow and the other is a delivery effect between holes.SOC CHEMICAL ENG JAPAN, 2006年08月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 39(8) (8), 807 - 813, 英語[査読有り]研究論文（学術雑誌）
- Hydrodynamics and heat transfer characteristics of drag-reducing trimethylolethane solution and suspension by cationic surfactantPhase-change slurry is a promising fluid for a district heating and cooling system. In this work, hydrodynamics and heat transfer characteristics of drag reducing trim ethy lolethane (TME: CH3C(CH2OH)(3)) solution and suspension by cationic surfactant were studied. Oleyl bishydroxyethyl methyl ammonium chloride (trade name: Ethoquad O/12) was used as the surfactant, while sodium salicylate (NaSal) as counter-ion. Two kinds of experiments were conducted, namely pressure drop/friction factor and heat transfer measurements. From friction factor measurements, it is found that surfactant can induce drag reduction (DR) in TME solution/suspension. It is also found that TME molecule reduces the DR capability. From heat transfer measurement, it is found that surfactant induces heat transfer reduction (HTR) in TME solution and suspension. It is also revealed that Colburn analogy cannot be applied for TME suspension or drag-reducing TME solution and suspension. By using a correction factor for the Colburn analogy, application of the analogy for the drag-reducing TME solution is improved. At low velocity, HTR is higher than the DR, but at high velocity (just before DR is lost) both HTR and DR are nearly the same.SOC CHEMICAL ENG JAPAN, 2006年06月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 39(6) (6), 623 - 632, 英語[査読有り]研究論文（学術雑誌）
- Evaluation of particle interaction for a gas-solid suspending systemIn particle handling processes the characteristics of powder flowability are important. Though there are various indexes, most of them were obtained from static measurements and have not been discussed the relationship with the circumstance effect. The flow behavior of a liquid is represented by viscosity. Especially for a liquid-solid suspension, it is well know that the viscosity changes according as the particle agglomeration. And the agglomeration or dispersion is dominated by the particle interaction. For a powder layer, however, its characteristics still have not been researched well. We have developed the method to measure the powder viscosity by uing FT-4 powder rehometer and clarified the flow characteristics and inter-particle interaction of silica powders. In this work, as test powders we used Talcum, calcium carbonate and crystalline cellulose powder in addition to silica powder, which are categorized by the Geldart classification from group C to A. Then the viscosities of all test powders decrease accompanied with the increase of the shear rate. This suggested that the particle agglomeration was broken down and the powder became easy to move at a high shear flow. On the other hand, the viscosity also decreased exponentially as the decrease of the solid volume fraction. And among test powders the dependency of the solid volume fraction on the viscosity can be clearly observed much larger than that of the rotating speed. It suggests that a particle population density affects the fragility of agglomeration remarkably more than a shear flow. To elucidate the dependency of the solid volume fraction on the powder viscosity quantitatively, the viscosity model for a solid-liquid suspension, Krieger-Dougherty Equation η /η 0 =(l-ø/ømax) ømax[η], were introduced and the intrinsic viscosity [η ] was adopted as an index of the particle interaction. The intrinsic viscosity for each powder calculated from viscosity data shows good correlation with the Geldart classification. Therefore we concluded well-known powder index for flowability may represent its dynamic characteristics and the powder viscosity has a possibility to provide us more detailed information of powder flowability.2006年, AIChE Annual Meeting, Conference Proceedings, 英語研究論文（国際会議プロシーディングス）
- Numerical computations on heat transfer characteristics in a cavity swept by hydrate slurry transported with visco-elastic fluidA two dimensional numerical study has been performed to investigate on heat transfer of hydrate slurry transported by a visco-elastic fluid in a cavity. In order to investigate the optimum geometric parameter, the effects of the rib height and the cavity length were changed in three steps, respectively. From the results, it is found that hydrate particles dispersed with Newtonian fluid (water) flow over the cavity without penetration. On the other hand, hydrate particles dispersed with visco-elastic fluid are observed effectively to penetrate into the cavity and sweep the bottom of cavity by Barus effect. Though the local heat transfer coefficient decreases in the downstream region of the cavity due to the development of thermal boundary layer, the mean Nusselt number on the cavity bottom in this visco-elastic dispersion medium cases becomes higher than that for water cases in corresponding cavity length. It was also found that heat transfer characteristics were significantly affected by cavity length for both dispersion medium cases. It is concluded that the visco-elastic dispersion medium causes effective heat transfer improvement in a cavity and that there exists the optimum geometry for the heat transfer augmentation in a cavity by using Barus effect.2006年, AIChE Annual Meeting, Conference Proceedings, 英語研究論文（国際会議プロシーディングス）

- Viscosity measuring technique for gas-solid suspensionsIt is important that we clarify the interaction between particles in particle processing. The interaction between particles tinder shear flow is considered to be evaluated by energy dissipation. i.e. viscosity, in a powder layer. By measuring the torque exerted on the mixing blade of a powder rheometer, the viscosity of the powder layer could be calculated. The viscosity decreased with the blade velocity and such a shear thinning rheological property is similar to that observed for solid-liquid suspensions. By applying the suspension rheology model. which was developed for the evaluation of the agglomeration state of solid-liquid mixtures under shear flow. particle agglomeration around the blade under dry powder flow conditions was evaluated. As the shear rate increases, the size of agglomerated particle clusters is proved to decrease. At high shear rate or low solid volume fraction, the inter-particle bonding energy is revealed to be constant independent of the shear rate and solid volume fraction.VSP BV, 2006年, ADVANCED POWDER TECHNOLOGY, 17(3) (3), 333 - 343, 英語[査読有り]研究論文（学術雑誌）
- Temperature and diameter effect on hydrodynamic characteristic of surfactant drag-reducing flowsHydrodynamic characteristic of surfactant drag-reducing flows is still not fully understood. This work investigated the temperature and diameter effect on hydrodynamic characteristic of cationic surfactant drag reducing flows in pipes. Solution of oleyl bishydroxyethyl methyl ammonium chloride (Ethoquad O/12), 900 ppm, as a cationic surfactant and sodium salicylate (NaSal), 540 ppm, as a counter-ion was tested at 12, 25, 40, and 50 degrees C in pipes with diameter of 13, 25, and 40 mm. Drag reduction effectiveness of this surfactant solution was evaluated in 25 mm pipe from 6 to 75 degrees C. Rheological characteristic of this solution was measured by stress control type rheometer with cone-and-plate geometry. Scale-up laws proposed by previous investigators were used to evaluate the flow characteristic of the Solution. It was found that this surfactant solution has clear DR capability until 70 degrees C. Result of this work Suggested that temperature has a significant influence in changing the hydrodynamic entrance length of surfactant drag reducing flows. From rheological measurement, it was found that the solution exhibits Shear Induced Structure at all temperatures with different degree of peak viscosity and critical shear rate.KOREAN SOC RHEOLOGY, 2005年12月, KOREA-AUSTRALIA RHEOLOGY JOURNAL, 17(4) (4), 157 - 164, 英語[査読有り]研究論文（学術雑誌）
- System analysis on absorption chiller utilizing intermediate wasted heat from micro gas turbine and solid oxide fuel cell hybrid systemA system analysis has been performed for the multi-effect absorption chiller (MEAC) applied as a bottoming system of 30kW class hybrid system including micro gas turbine (MGT) and solid oxide fuel cell (SOFC) hybrid system. In this paper, an intermediate wasted heat utilization (IWHU) system is suggested for lifting up the energy efficiency of the whole system and coefficient of performance (COP) of MEAC. From the results, the suggested IWHU system was found to show the very high energy efficiency compared with a terminal wasted heat utilization (TWHU) system that uses only the heat exhausted from the terminal of MGT/SOFC system. When TWHU system is applied for MEAC, the utilized heat from the MGT/SOFC system is found to remain low because the temperature difference between the high temperature generator and the wasted heat becomes small. Then, the energy efficiency does not become high in spite of high COP of MEAC. On the other hand, the IWHU system could increase the utilized heat for MEAC as performs effectively. The exergy efficiency of IWHU system is also revealed to be higher than that of a direct gas burning system of MEAC, because the wasted heat is effectively utilized in the IWHU system.2005年, AIChE Annual Meeting, Conference Proceedings, 10835 - 10851, 英語研究論文（国際会議プロシーディングス）
- Mixing characteristics of high viscous fluid by a multi-holed static mixerThe mixing characteristics of a multi-holed static mixer have been studied for high viscous fluid. A multi-holed static mixer composed of five pairs of 4- and 5-hole elements. Each hole has the diameter of 6mm at its inlet and outlet, d[m], and the size of straight part of the hole, a[m], was changed in two steps of 2mm and 5mm. The fluid viscosity and fluid velocity are also changed as parameters. Flow visualization experiments in a test pipe with 18mm diameter was performed in order to observe the occupation ratio of dyed fluid, which is injected from the nozzle with 4mm diameter mounted in the upstream of the static mixer and flows through the static mixer, and to reveal the mixing mechanism of the present system. From the results, it is found that the Reynolds number based on the mean velocity in the 4 hole element and the hole size, Re a[-], divided by a contraction ratio of the hole, a/d, well correlates the mixing and pressure loss characteristics. From the flow visualization in the hole, it is observed that the twin vortices are formed and that they have a spiral structure. This flow structure is intensified by the increase of the velocity. Then, this is concluded to be the mixing mechanism of the present system.2005年, AIChE Annual Meeting, Conference Proceedings, 4089 - 4105, 英語研究論文（国際会議プロシーディングス）

- スピンコートによる単分散粒子凝集スラリーの構造制御The structure of mono-modal spherical particle sols was controlled by changing the rotation rate of the spin coating. The number of cluster formed in the spin coated layer was counted. The apparent viscosity of particle (13 mu m dia.) sols was measured, and the cluster size and number of primary particles contained in the Cluster were predicted by the Usui's Suspension model, which makes assumption that multi-breakup of inter-particle bonding Occurs when a cluster breaks into two parts under a simple shear flow by spin coating. It was certified that the maximum packing volume fraction for particles can be Successfully used to predict the Slurry viscosity, and this means indirectly the maximum packing Volume fraction determined in this study may be reasonable. Good agreement of the number of Cluster between experimental data and the prediction was obtained. This means that the Usui's model can be used to predict the controlled Structure of particles in spin coating technology.SOC RHEOLOGY, JAPAN, 2005年, 日本レオロジー学会誌, 33(5) (5), 279 - 283, 英語[査読有り]研究論文（学術雑誌）

- Characteristics of the laminar flow induced by reciprocating a disk impeller in a cylindrical vessel have been investigated by combining LDA velocity measurements with CFD calculations. From the variations of velocity fluctuation with Reynolds number, it is found that transition from laminar to turbulent flow takes place at Re = 2 × 102. The flow at 20 < Re < 2 × 102 is two-dimensional without producing tangential velocity component, and a vortex is generated behind the disk impeller. With increasing Reynolds number the center of the vortex departs from the disk edge and the vortex is elongated and strengthened in the rear region of the disk impeller. CFD calculations have been carried out for the case where the existence of the shaft is ignored. The velocity variations near the reciprocating disk are well represented by CFD calculations, which are symmetric between the upward and downward stroke except a small disk or small contraction of the flow through the gap. Influences of the narrow gap between the disk edge and the vessel wall and those of the shaft on the force acting on the disk are investigated by comparing the calculations with the measured data.The Society of Chemical Engineers, Japan, 2001年07月, Journal of chemical engineering of Japan, 34(7) (7), 919 - 928, 英語
- Characteristics of turbulent flow induced by reciprocating disk in cylindrical vesselVelocity measurements have been conducted in order to examine characteristics of turbulent flow induced by reciprocating a disk impeller in a cylindrical vessel. Variations of the average velocity fluctuation show that the transition regime from laminar to turbulent flow is located at 2 x 10(2) < Re < 4 x 10(2). In turbulent flow regime, a circulating flow with radial and axial velocity components is generated in the rear region of the disk. At a moderate Reynolds number a secondary circulating flow is induced behind the original circulating flow, but at a sufficiently high Reynolds number the region of the original circulating flow elongates without generating such a secondary circulating flow. Turbulence level is much higher in the circulating now region than in the front region of the reciprocating disk. The fluctuating velocity components in the radial, tangential and axial directions show similar periodic variations to each other irrespective of the magnitude of the Reynolds number, and the maximum fluctuating velocities attains about the same magnitude of the maximum disk velocity. The flow pattern and the magnitude of turbulence change violently during one cycle of reciprocation. In addition, at a sufficiently high Reynolds number, circumferential circulation of the fluid appears in the front and rear regions near the disk, whose direction is opposite to each other. The excellent mixing performance of recipro-mixing in turbulent flow regime is reasonably explained by these findings.SOC CHEMICAL ENG JAPAN, 2001年07月, JOURNAL OF CHEMICAL ENGINEERING OF JAPAN, 34(7) (7), 929 - 935, 英語[査読有り]研究論文（学術雑誌）

- 0109 急縮小流路内流れにおけるサスペンション中微粒子の凝集・分散挙動Control of aggregation/dispersion behavior of fine particles in a suspension is important to improve characteristics of complex materials. The dispersion behavior of fine particles in a suspension was observed and analyzed in a flow across sudden contraction in a microchannel. The dispersed particle and media of the suspension were polystyrene (diameter: 3:5 μm) and 27:0 wt% aqueous glycerol solution. The volume fraction was 0.02. The suspension was introduced to the microchannel using syringe pump. The velocity and dispersion behavior of fine particles of the suspension were determined in the PIV and image analysis. As a result, the velocity profile was fully developed at x/H = 0:23. The profile of the mean number of particles in a cluster at x/H = 0:24 was equal to the profile at upper stream. At x/H = 0:74, the mean cluster size was smaller than that at x/H = 0:24 It indicates a difference in the entrance region of the velocity field and aggregation/dispersion characteristics.一般社団法人日本機械学会, 2015年11月07日, 流体工学部門講演会講演論文集, 2015, "0109 - 1"-"0109-2", 日本語
- 0110 マイクロキャビティを掃引する粘弾性流体の不安定流動特性Instability characteristics observed in a micro-cavity swept by a visco-elastic fluid has been investigated. Surfactant solution used as a viscoelastic fluid was inserted in a micro-cavity whose length, depth and wide low path were set constant at 1, 0.2 and 0.4 mm, respectively. The time variation of the tonguing motion of the separation bubble formed in the downstream region in the cavity was measured when the Reynolds number defined with water viscosity, cavity depth and the mean velocity in a narrow flow path was change in three steps: 1, 5 and 20. From the results, it was found that the fluctuation time scale is from 1.9 to 4.5 s, which is located between the middle and longest relaxation times. It was also found that the time scale does not depend on the Reynolds number.一般社団法人日本機械学会, 2015年11月07日, 流体工学部門講演会講演論文集, 2015, "0110 - 1"-"0110-2", 日本語

- S0520203 粘弾性流体により掃引されるマイクロキャビティ内の不安定流動([S052-02]複雑流体の流動現象(2))Flow characteristics of visco-elastic fluids sweeping a micro-cavity mounted in a micro-duct have been investigated in order to develop a novel technique of a mixing process for micro-reactors. In this paper, effects of the Reynolds number and of the rheological characteristics of the fluids were focused on. The cavity depth, the cavity length and the width of the wider flow path were fixed at 200, 1,000 and 400 u,m, respectively. As a visco-elastic fluid, a solution of cationic surfactants with counter-ions was used. The molar ratio of counter-ions to surfactants was changed in four steps in order to change the rheological characteristics of the visco-elastic fluids. The Reynolds number was also changed from 0.100 to 100. From the results, it was found that a tonguing motion of the separation fluid bubble tip formed in the downstream region in the cavity occurs at a certain Weissenberg number larger than 200 due to the elastic instability. The fluctuating bulge structure was also observed on the upstream side wall of the cavity in a higher range of the Weisenberg number. Such an elastic instability can be expected a suitable micro-fluid motion for the micro-mixing.一般社団法人日本機械学会, 2014年09月07日, 年次大会 : Mechanical Engineering Congress, Japan, 2014, "S0520203 - 1"-"S0520203-6", 日本語
- J0440105 乱流抑制効果を溶液中の高分子が受ける流動抵抗実測により考察する試験的研究([J044-01]ソフトマター・イノベーション(1),機械材料・材料加工部門)Solution containing little amount of polymers shows complex behavior, such as drag reduction effects and elastic turbulence. These phenomena are due to viscoelasticity of polymers. However, little study has been made to measure a relationship between polymers and solution directly. In this study, we have tried to measure frictional drag of polymers added by fluids. In order to measure it, Atomic Force Microscope (AFM) was used. Polymers having a thiol group at the terminus were attached to a gold-coated cantilever of the AFM. The cantilever was swept in solution. When polymers were attached to the cantilever, the cantilever detects additional force due to polymers. It was assumed that the polymers cover the cantilever as saturated adsorption, and all polymers induce force due to Stokes drag. This force was calculated by Stokes equation, which is indeed reasonably fit to the force measured by AFM.一般社団法人日本機械学会, 2014年09月07日, 年次大会 : Mechanical Engineering Congress, Japan, 2014, "J0440105 - 1"-"J0440105-3", 日本語

In this model, it was considered that an aggregation/dispersion rate depends on Brownian coagulation, shear coagulation and shear breakup. Immersed boundary method was used to calculate a flow with rotating rotor. The diameter of the cylinder was 38 mm. The major and minor axes of the elliptical rotor were 32 and 26.6 mm. The rotor was rotated at 20 RPM. The diameter of particles and the viscosity of disperse media were 2.5 ?m and 195 Pa s. As a result, the cluster was broken by applying shear and the size of cluster decreased with time. The particle dispersion behavior varies with local position. The mean cluster size took a minimum value right after the major axis of the rotor passed. Then the mean cluster size increased again.一般社団法人日本機械学会, 2013年11月09日, 流体工学部門講演会講演論文集, 2013, "0101 - 01"-"0101-02", 日本語
- S051015 粘弾性流体中のマイクロバブル曳糸効果([S051-01]複雑流体の流動現象(1))The characteristics of oxygen-dissolution accelerated by use of micro-bubbles in a viscoelastic fluid have been studied. An aqueous solution of a combination of a cationic surfactant and of a counter-ion supplier was used as a viscoelastic fluid. Flow visualizations and the time-variation of oxygen concentration measurements were performed. From the results, it was found that the dissolution of oxygen rapidly occurs by use of micro-bubbles, but that the dissolution becomes slow in a high elastic fluid. The flow observation of bubbles in a high elastic fluid showed a chaining effect with the bubble ascension. The bubble chaining accelerates agglomeration of bubbles and decreases apparent gas-liquid interface area. Thus, such a chaining effect was concluded to disturb the dissolution of oxygen.一般社団法人日本機械学会, 2013年09月08日, 年次大会 : Mechanical Engineering Congress, Japan, 2013, "S051015 - 1"-"S051015-5", 日本語
- J044041 マイクロダクト内気液界面を用いたリポソーム生成法([J044-04]ソフトマター・イノベーション(4))Liposomes produced from lipids have been studied as promising materials for a drug delivery system (DDS), since the liposomes are relatively non-toxic and biodegradable. For using liposomes as a drug carrier, the size of liposomes and the homogeneity in their structure are the most important characteristics. In this study, a novel technique of liposome production using a gas/liquid interface in a T-shape micro-duct has been suggested. By this method, the liposomes can be obtained without harmful organic solvents and the miniaturization of liposome production can be realized. The behaviors of gas columns and liquid columns in the micro-duct were changed depending on flow rate. Diameters of the liposomes were decreased by increase of the flow rate. The diameters of liposomes seemed to be affected by the length of liquid columns.

- 1103 二次元石鹸膜内乱流における波数変動特性に関する研究(OS11 非ニュートン流体の流動現象,オーガナイズドセッション)An experimental study has been performed in order to investigate the relationship between the extensional viscosity of polymers and the turbulent drag reduction.Polyethyleneoxide as a flexible polymer and hydroxypropyl cellulose as a rigid rod-like polymer were added to the two-dimensional turbulence that was visualized by the interference pattern of the flowing soap films and analyzed by an originally-developed single-image analysis.The power spectra of interference images were obtained,which is related to the water layer fluctuations in turbulence.The power spectra show a scaling behaviour and the power components give the information of drag reduction.Wavelet-coefficient was also calculated.It was found from these results that the energy transfer mechanisms are different in streamwise and normal directions.In the normal direction,the energy transfer is prohibited by the orientation of polymers,while the energy transfer in the streamwise direction is prohibited by extensional viscosity of polymers.The characteristic scales for the energy transfer were also observed as a periodic structure in Wavelet-coefficients.一般社団法人日本機械学会, 2012年11月16日, 流体工学部門講演会講演論文集, 2012, 413 - 414, 日本語

- 1602 非一様せん断流動場における微粒子分散特性の数値計算(OS16-1 非ニュートン流体の流動現象,オーガナイズドセッション)A particle dispersion model calculating local particle agglomeration characteristics of a solid/liquid suspension has been developed. In a model, not only the effects of Brownian and shear agglomerations and shear break-up but also the convective effects by local velocity components in a flow were taken into consideration. With this model, the local agglomeration characteristics in a suspension with various solid fractions were computed for a flow between parallel plates. The present model shows that the high agglomeration causes in a center region of the flow between parallel plates where low shear is added, and that the viscosity becomes high there. From this, it is concluded that the present model leads to a reasonable result on the particle agglomeration characteristics and a promised tool for estimating local particle agglomeration and viscosity characteristics in a flow.一般社団法人日本機械学会, 2010年10月29日, 流体工学部門講演会講演論文集, 2010, 459 - 460, 日本語
- 非イオン性界面活性剤添加水溶液の抵抗低減とレオロジー特性(非ニュートン,一般講演)Experimental studies on drag-reducing and rheological characteristics of nonionic surfactant have been performed by the measurement of pressure drop in a 5mm diameter pipe flow, shear viscosity and shear stress reflaxtion. Alkyl polyglucoside GLUCOPON 600 CS UP and oleyldimethylamineoxide ODMAO were used as nonionic surfactants. It is found that the immediate causal connections are absent both between shear-induced structure (SIS) and turbulent drag reduction, and between SIS and viscoelastic effects. In addition, a strong viscoelastic effect is not always needed to obtain turbulent drag reduction in some cases, based on these measurement results.日本流体力学会, 2010年, 日本流体力学会年会講演論文集, 2010, 277 - 277, 日本語

The contributions from each structure were estimated while the surfactant concentration and the counter-ion molar ratio to the surfactants were widely changed. From the results, it was found that the structure having shortest relaxation time well corresponds to the shear stress characteristics. Form the comparison with the drag reduction occurrence map, the shortest relaxation structure was concluded to be the main cause of drag reduction occurrence.一般社団法人日本機械学会, 2009年11月06日, 流体工学部門講演会講演論文集, 2009, 217 - 218, 日本語

- 粘弾性流体を用いた多段キャビティを有する複雑流路内の流動特性(反応・多相系 非ニュートン,一般講演)Two-dimensional numerical computations have been performed in order to investigate flow characteristics in multiple cavities when a visco-elastic fluid is used as a working fluid. Twenty-four cavities were mounted in a one-side surface of a flow path between parallel plates. The Reynolds number, cavity length and depth were set at constant values of 100, 50mm and 20mm, respectively. From the results, it was found that the fluid penetrates into each cavity because the Barus effect occurs in each cavity. On the other hand, the large vortex was formed on each opposite side at each cavity. The pressure loss in the case of visco-elastic fluid becomes 35 times higher than that in case of water due to its high viscosity. However, the viscosity effect on pressure loss was found to be reduced by some vortices effects.日本流体力学会, 2009年, 日本流体力学会年会講演論文集, 2009, 228 - 228, 日本語

The friction coefficient in a pipe flow of hydrate slurries treated with surfactants was at first measured. From the results, it was found that the effective drag reduction appears in the cases of high surfactant concentration and of high hydrate fraction. This behavior was supported by the viscosity shear-thickening occurrence reported in the previous study. However, the effective drag reduction disappears in the case of low surfactant concentration in spite of the shear-thickening occurrence. On this discrepancy, the relaxation time of the solution was measured. It is found that the critical concentration determined from the relaxation time disappearance well corresponds to limitation of effective drag reduction occurrence.一般社団法人日本機械学会, 2007年11月17日, 流体工学部門講演会講演論文集, 2007, "606 - 1"-"606-4", 日本語
- E214 粘弾性流体によって掃引されるキャビティ内の熱伝達特性(OS-9 単相混相機能性流体の流動と熱伝達I)In order to investigate the optimum geometric condition for a heat transfer augmentation technique using the Barus effect of visco-elastic fluid, heat transfer experiments have been performed in a cavity. In this paper, the length of a cavity mounted on one side in a channel flow was changed from 50mm to 200mm. The results indicated that the mean Nusselt number on the cavity bottom in the cases of visco-elastic fluid becomes smaller than that in the corresponding cases of water under the present conditions, but it was found that the visco-elastic fluid improved heat transfer characteristics behind the upstream wall of the cavity at least.一般社団法人日本機械学会, 2005年11月02日, 熱工学コンファレンス講演論文集, 2005, 413 - 414, 日本語
- E224 機能性流体によって輸送される潜熱微粒子スラリーの伝熱促進(OS-9 単相混相機能性流体の流動と熱伝達II)A Numerical study has been performed in order to investigate the heat transfer characteristics of a hydrate slurry transported by a visco-elastic fluid flowing between parallel plates with a one-sided cavity. The length were changed in three steps from 50 to 200mm, while the rib height, rib length and the width of wide flow path were fixed. The results were compared with those in the case when water is used as transportation media of hydrate particles. From the results, it is found that hydrate particles flows over the cavity without penetration in the case when solvent is Newtonian fluid (water). On the other hand, hydrate particles are observed effectively to penetrate into the cavity by Barus effect in the case of visco-elastic solvent. This causes effective heat transfer from the bottom wall of the cavity.一般社団法人日本機械学会, 2005年11月02日, 熱工学コンファレンス講演論文集, 2005, 421 - 422, 日本語

The cavity depth, cavity length and bulk velocity was changed while the wide path and rib length was kept constant. From the results, three flow patterns without and with one or two recirculating regions are observed. The second separation is found to be caused by the flow contraction at the downstream end of the cavity. Additionally, it is found the first separation is governed by the narrow path flow Reynolds number and expansion ratio.日本流体力学会, 2005年, 日本流体力学会年会講演論文集, 2005, 33 - 33, 日本語
- AM05-01-004 抵抗低減流の速度変動場に対する対イオン濃度の影響(乱流現象の制御・流れの抵抗低減1,一般講演)An experimental study has been performed in order to investigate the effect of counter-ion concentration on the flow fluctuation and time characteristics of drag-reducing cationic surfactant solution. The molar ratio of the counter-ion to cationic surfactant additives was changed from 1.5 to 100. From the results, the high fluctuating intensity is found to markedly decrease with the concentration of counter-ion. This flow laminarization occurrence is a main cause on the drag reduction occurrence. When the concentration of counter-ion increases, the relaxation time decreases down to 0.1s order. It is concluded that this time scale observed in the case of high concentration of counter-ion is deeply related to the drag reduction occurrence.日本流体力学会, 2005年, 日本流体力学会年会講演論文集, 2005, 44 - 44, 日本語
