    Abstract Rapid cooling of reactants quenches the intermediate state of chemical reactions and enables the synthesis of novel materials that cannot be realized by thermodynamic equilibrium processes. In this study, we estimated the cooling rate of reactant solutions during the supercritical hydrothermal synthesis of metal oxide nanoparticles. Neutron radiography measurements were performed to visualize the profile of the average water density at a junction where a stream of heated water was mixed with another stream of cooling water. The cooling rate of the heated water that mimicked the reactant solution was estimated using the relationship between the density and temperature of water under constant pressure conditions. This result should provide vital information about the flow-type synthesis of novel metal oxide nanoparticles.

  • A new method for high flow rate measurement using ultrasonic multi-wave pulsed Doppler method with staggered trigger
    Ei Muramatsu, MURAKAWA Hideki, SUGIMOTO Katsumi, TAKENAKA Nobuyuki
    Ultrasonic pulsed Doppler method is a powerful tool to measure velocity distribution in a flow field. However, the method has the maximum measurable velocity. In addition, the measurement volume of this method is relatively large and it is known that the measurement volume affects measured velocities in near-wall region. To measure higher velocity, feedback method which is a dealiasing method and a multi-wave ultrasonic transducer were introduced. Using the transducer, velocities in the near-wall region were measured by 8 MHz ultrasonic with small sensor diameter, velocities far from the transducer were measured by 2 MHz ultrasonic with large sensor diameter. Thus, measurement volume was minimized in the near-wall region. Experiments were carried out at flow rate calibration facility at AIST, and the effects of the measurement volume and the number of pulse repetitions for obtaining an instantaneous velocity profile, N_, was discussed. As a result, reduction of the measurement volume improved measurement accuracy in the near-wall region by using the multi-wave transducer, and the measurement accuracy of flow rate was improved. Increasing the N_ was found to be effective for improving the measurement accuracy even though the total echo signals are the same for calculating the average velocity distribution.

    Variable Conductance Heat Pipes (VCHP) are used as a cooling device which can passively keep the evaporating temperature by enclosing non-condensable gas (NCG) with refrigerant. The VCHP has often a bend section between evaporating and condensing area, since the condensation section should be placed vertically above the evaporation section. It is known that the bend may disturb a liquid flow to the evaporation section. The effect of the VCHP orientation, filling ratio of the refrigerant, amount of the charged NCG have been examined. A thin plate was inserted to more the effects of the bend. In this study, the refrigerant behaviors in the VCHP with the bend were diagnosed based on flow visualization by neutron radiography. It was observed that liquid plugs formed at the bend and suppressed the condensed liquid supply to the evaporating section without the thin plate. It was also shown that the thin plate inserted in the bend was effective to avoid the liquid plug formation.

    A self-vibration heat pipe having a meandering capillary tube can operate on top and horizontal heat mode without gravity effects. However, the behaviors of the working fluid in the pipe have not been well studied. In this study, the working fluid in the self-vibration heat pipe was visualized by neutron radiography system in Japan Atomic Energy Agency. The liquid columns formed in the cooling area were visualized at 200 frames/s in the meandering channel. Image processing methods to show the vibration of the liquid column were developed. It was shown that the liquid columns were vibrated around the cooling area and supplied to the heating area. The heat was transported from the heating area to the cooling area. The maximum effective thermal conductivity of the plates were about 20 times of aluminum. The flow pattern was evaluated at the volumetric ratio of liquid phase in the heat pipe. The periods of the vibration were predicted fairly well by a mass-spring model.

    Boiling heat transfer enhancement is efficient for development of a cold plate used in a two-phase flow loop type thermal control system. This study deals with boiling heat transfer enhancement for a narrow channel by thermal spray coating of metal. Copper particles were coated on the heating surface by vacuum plasma spraying. Two kinds of surface were manufactured using different particle size, about 200 and 50 µm. The heat transfer performance was evaluated in saturated flow boiling experiments of HCFC123 for ranges of mass flux of 100 to 400 kg/(m2•s), inlet quality of 0 to 0.60, and heat flux of 25 to 251 kW/m2. The test channel with the width of 20 mm, and heated length of 100 mm was placed horizontally. The lower side of heating area was heated by cartridge heaters through a copper block. The channel gap was set to 2 and 4 mm. As the result, the coating surface produced higher heat transfer coefficient than the smooth surface, especially, the heat transfer performance of the surface using finer particle was higher and was about 5 to 10 times higher than that of the smooth surface. While the effect of gaps on the heat transfer coefficient was a little, the critical heat flux increased with increasing the channel gap. Critical heat flux was increased a little by thermal spray coating.

    A two-phase flow thermal control system, which utilizes the latent heat of fluid, is paid attention to for the heat removal in the space station and the Space Solar Power System (SSPS). The characteristics are that the system weight is lower than that in single-phase flow and that the temperature can be controlled by changing the saturated pressure of the loop. The control technology of the system has not been put into practical use. It is very effective to estimate the dynamic response of the loop by the numerical analysis as a means to establish the control technology of the thermal control system utilizing latent heat. The simulation model of the system was constructed, and the results of the numerical analyses were compared with the experiment results. A good agreement between analytical and experimental results was obtained.

  • Microgravity Two-Phase Flow Characteristics in Adiabatic Pipes
    Buhong CHOI, FUJII Terushige, ASANO Hitoshi, SUGIMOTO Katsumi
    More reliable design of thermal transport, power acquisition and thermal control/management systems for space use requires a through understanding of the flow hydrodynamic, the differences and similarities between the two-phase flow characteristics of two-phase flow influenced by the change in gravity. The data of flow patterns, void fraction, frictional pressure drop associated with its characteristics were obtained at normal gravity and in microgravity and hyper-gravity (2g) conditions aboard MU-300 aircraft capable of parabolic trajectory flying. Some experiments were performed for an air-water two-phase flow through 10mm diameter adiabatic test section with 600mm length of transparent acrylic resin horizontal tube. The obtained experimental data covered a range of liquid and gas flow rates with the liquid superficial velocity ranging from 0.095m/s to 2.56m/s, and the gas superficial velocity ranging from 0.032m/s to 21.08m/s. The results obtained at three gravity levels (μg, 1g and 2g) are compared with some of the existing models and correlations. Flow pattern results obtained under μg, 1g and 2g conditions were compared with void fraction based flow pattern transition models developed by Bousman (1995). In the comparisons of the microgravity void fraction results with the correlation proposed by Inoue-Aoki (1970), it was found that the micorgravity void fraction was greater than the model as 42% for bubbly flow region. Two-phase frictional pressure drops obtained under three g-levels were compared with each other, and it also showed that frictional pressure drop were well fitted with the Lockhart-Martinelli-Chisholm model. As results, the gravity dependency of flow patterns was more clearly appeared with the decrease in gas and liquid flow rates. The effect of gravity on two-phase flow frictional pressure drop was insignificant for the turbulent flow regions.

  • A Study of High Performance Gas-Liquid Phase Separator by Utilizing Y-junction under Microgravity Condition
    YE Shuang, FUJII Terushige, ASANO Hitoshi, SUGIMOTO Katsumi
    Gas and liquid phases are easily separated owing to buoyancy on the ground. However, in space (i.e. under micro-gravity condition), the method cannot be adopted. In this study, a method of a Y-junction by using the difference of inertia force between gas and liquid phases is proposed for a first-step and rough separation. Experiments of phase separation in a horizontally placed impacting Y-junction were carried out under both normal and micro-gravity conditions. Phase separations in Y-junction for two-component and one-component two-phase flow were also examined. As a result, it was shown that the liquid could be extracted effectively from the two-phase flow by using a Y-junction under micro-gravity. The effect of inlet flow pattern of gas-liquid flow on phase separation performance was discussed.

  • A Study of Renewable Energy Hydrogen-Fired Power Generaion Plants.
    Mohammed Ghiyath Soufi, FUJII Terushige, SUGIMOTO Katsumi, ASANO Hitoshi
    The world's population is expected to increase to ten billion in the 21^ century, accompanied by a rapid increase of energy consumption. This will bring about a shortage of fuel resources and global warming caused by CO_2 emissions. The basic solution to these problems will be to use energy resources more efficiently and to switch from fossil fuels to nuclear energy and renewable energy. On this purpose in this paper we will propose the hydrogen-fired Rankine cycle as similar to (C) type and then we will make modification of it by increasing the performance characteristics and efficiencies with (reheating, regenerative and recuperation) of the working fluid of the bottoming cycle respectively, and in this case we will present two types (C1 and C2). In case of type C2 the cycle will be called as "New Rankine Cycle". And as well these cycles will be compared with the Rankine cycle (C) for hydrogen-fired, to show the advantages of the performance characteristics of the new design which the highest value of exergy efficiency can be reached to 63.58% as HHV at 1700℃ of the combustor discharge temperature. These cycles will be analyzed by thermodynamic theory as well as for exergy analysis, and the performance characteristics of the cycles will be studied. The effects of the different parameters such as the discharge temperatures and pressures of the combustors of high and low pressure and also the effect of pressure of the condenser on the performance of the cycles will be also clarified.

    In order to investigate the flow and hydrodynamic characteristics of two-phase flow influenced by the change in gravity, tests were performed using MU-300 flight capable of producing μg and 2g conditions and on ground with the identical flow conditions and the same flow loop. The test section was a 10mm diameter and 600mm lengths, and it was also mounted horizontally to the direction of gravitational force. The ranges of superficial velocity are 0.1m/s to 2.6m/s for water, 0.03m/s to 21m/s for air, respectively. The data collected at three gravity levels (μg, 1g and 2g) were compared with the existing models and correlations, and the differences and similarities between the two-phase flow characteristics at three gravity levels were also presented.

    Hydrogen, which does not generate CO_2 by combustion, is considered to be an important (clean) energy source in near future. In the middle of 21st century, hydrogen energy society may be realized. In this study, several distributed hydrogen energy systems, which use hydrogen produced by water electrolysis, are dealt, and the energy costs for each system are evaluated. As a result, the energy cost using Brown's gas is greater than that of using the town gas in the case of present cost of equipment. However, in the case of 50% of the cost of equipment and cost of town gas of 100 yen/m^3, the case of Brown's gas is nearly equal to the case using town gas.

The two-fluid cycle is dealt with for municipal solid waste(MSW)-burnt power generation, in which the bottoming cycle using C_6H_6, and C_6H_<12> and so on as the working fluid against water in the topping cycle. The performance characteristics of the two-fluid cycle were investigated and compared with those of the single Rankine cycle with the moisture separator. As the result, the optimum plant's thermal efficiency of the two-fluid cycle using C_6H_<12> as the bottoming working fluid is increased by about 1.4% compared with that of the single Rankine cycle with the moisture separator under the main steam temperature of 395℃, and it reaches 24.2%.

    The two-fluid cycle is considered for municipal solid waste (MSW) -burned electric power generation, using six kinds of working fluid such as NH_3, C_5H_12, C_6H_6, and H_2O at the bottoming cycle. The performance characteristics of the two-fluid cycle are obtained at topping steam temperatures of 395 and 495℃. The optimum cycle conditions, which maximize the plant's thermal efficiency, are determined for the respective working fluid. It is shown that the plant's thermal efficiency of the two-fluid cycle was increased to 25.3% from 19.0%, using C_6H_6 as the working fluid under the main steam temperature of 395℃ by superheating the bottoming vapor.

  • 0402 Effect of velocity extension on the velocity accuracy using ultrasonic pulsed Doppler method
    HASHIGUCHI Daiki, MURAMATU Ei, MURAKAWA Hideki, AUGIMOTO Katumi, ASANO Hitoshi, TAKENAKA Nobuyuki, FURUICHI Noriyuki
    Ultrasonic pulsed Doppler method (UDM) can obtain velocity profile along the ultrasonic beam path. However, the UDM has the limitation of the detectable velocity based on the measurement volume size. This problem was apparent when higher velocity were measured by using a velocity extension method. In order to investigate the accuracy of the velocity extension method, velocity distributions in a rotating cylinder were measured with changing of the measurement volume, and the relation between the maximum velocity required for the reflector to remain in the same measurement volume during the pulse interval, ν_, and the measured velocity was investigated. It was found that if measured velocities were higher than the ν_, the velocity accuracy dramatically decreased. Further, the tendency was more apparent with going away from the transducer.

  • 1701 Evaluation of local void fraction in two-phase flow around tubes in horizontal bundle
    BABA Misaki, MURAKAWA Hideki, SUGIMOTO Katsumi, TAKENAKA Nobuyuki, ITO Daisuke, Saito Yasushi
    Measurements of void fraction distribution around tubes across horizontal tube bundle in liquid-gas two-phase flow were carried out using X-ray radiography system. Under bubbly flow condition, it was observed that bubbles mainly passed through the vertical tube gaps and accumulated on the upstream side of the tubes. Also it was observed that void fraction was lower around the wall side tubes than that the center tubes. Measurements results of the void fraction were underestimated comparing to the previous studies. Because void fraction near the wall is lower than that in the center-region. Thus, cross-sectional averaged void fraction decreased comparing to the void fraction which was averaged except for the near-wall region.

  • H222 A study of heat transfer characteristics of oscillating heat pipe
    Oka Nobuyuki, Sugimoto Katsumi, Takenaka Nobuyuki, Asano Hitosi, Murakawa Hideki
    This study experimentally investigated the heat transfer characteristics of oscillating heat pipe (OHP). The OHP was made of copper flat plate, and its flow pattern can be visualization. This OHP had 20 parallel channels. In this study the working fluid was ethanol. The installed condition of the experimental apparatus were performed at horizontal and vertical. As a result, the oscillation frequency of the liquid column increased with the heat input increase, and the effective thermal conductivity is increased. The liquid supply to the heating area a vertical condition was sufficient by gravity. Therefore the maximum effective thermal conductivity of the vertical condition and the horizontal condition was about 15 times and 12.5 times that of copper.

  • F112 Development of multi-wave ultrasonic pulsed Doppler method for higher flow rate measurement
    MURAMATSU Ei, MURAKAWA Hideki, SUGIMOTO Katsumi, TAKENAKA Nobuyuki, FURUICHI Noriyuki
    As ultrasonic pulsed Doppler has many advantages, it has been widely used for measuring velocity profiles. By integrating the obtained velocity profile all over the pipe, flow rate can be derived. The authors have developed feedback method which is a dealiasing method for high flow rate measurement and reported that measurement accuracy was improved by applying a multi-wave ultrasonic transducer. In this paper, effect of the size of measurement volume was investigated analytically and experimentally. In the analysis, measured velocities were considered to be ensemble average over the measurement volume. Analytical results showed the effect of channel-width was more significant than that of the sensor diameter. Furthermore, results of experiments were in good agreement with the analysis.

  • A232 A study of fluid phenomena in a downward branch pipe with a closed end : Fluctuation mechanism for penetration depth
    MIYOSHI Koji, TOKURA Takahiro, MAEDA Shogo, SUGIMOTO Katsumi, TAKENAKA Nobuyuki, Nakamura Akira
    Hot water in a main pipe flows into a branch pipe and forms a thermally stratified layer with cold water at a bent section. Fluctuation of the thermally stratified layer may initiates thermal fatigue crack in the branch pipe. It has been reported that the fluctuation of penetration depth induced by the main flow in the branch pipe with a closed end was caused by generation of a large swirl flow at L = 4D_b. Experiments with the rectangular and reduced branch pipes were conducted to suppress the fluctuation of penetration depth induced by the main flow. It was shown that the fluctuation of penetration depth in the rectangular pipe was suppressed, because the large swirl flow at L = 4D_b was not formed. It was also shown that the rectangular and reduced branch pipes were available to decrease the penetration depth by the main flow in the branch pipe.

  • A231 Effects of Non-condensable Gas on Temperature Fluctuation Phenomena in Pressurizer Spray Pipe of Pressurized Water Reactor

    Steam-water two phase flow is present in normal operating condition in the horizontal part of the pressurizer spray pipe of PWR. High cycle fatigue crack generation is a concern under the conditions of such thermally laminar two phase flow, wherein temperature fluctuation under of steam-water interface is caused by internal gravity waves in thermal stratified flow. In this study the effect of non-condensable gas to the temperature fluctuation of thermal stratified flow was investigated by the experiments using visualization test section of rectangular pipe. As a result, temperature distribution and fluctuation were roughly divided into three patterns by the amount of the non-condensable gas.

    WADA Daisuke, MURAKAWA Hideki, SUGIMOTO Katsumi, ASANO Hitoshi, TAKENAKA Nobuyuki
    Fuel gas (hydrogen gas) and oxidant gas (air) are supplied to a Polymer Electrolyte Fuel Cell (PEFC) in saturated moist condition to keep a membrane wet. Condensation may occur in the cathode side, since the air is super-saturated by the fuel cell reaction. If the condensed water stay in an electrode, Gas Diffusion Layer (GDL) or gas channels, it may affect on the fuel cell performance. In this study, dynamic CT technology which performed 1 CT per 1 sec was developed, and visualization of three-dimensional water distributions in an operating PEFC was measured by using neutron dynamic CT. As a result, it was confirmed that the developed system can measure three-dimensional water distribution in the PEFC and, condensed water had a significant influence on the fuel cell performances.

    Ozawa Shogo, Nishimura Takuya, Matsumoto Koji, Takenaka Nobuyuki, Sugimoto Katsumi
    The drag reduction by using surfactant is expected to contribute for saving energy in heat exchangers. Measurements of pressure drop and heat transfer were conducted to investigate the heat transfer characteristics of the drag reduction with changing the mole ratio ξ and the concentration of the solution. The drag reduction effect was obserbed under the conditions of over 300ppm of the solution at ξ =10. The pressure drop decreased with increasing of the surfactant concentration. Heat transfer coefficient decreased when the drag reduction occurred. Corburn analogy was applicable to the experimental results for low flow velocity conditions.

    Kamata Yohei, Murakawa Hideki, Sugimoto Katumi, Asano Hitoshi, Takenaka Nobuyuki, Shiozawa Masahiro
    This paper presents a new measurement technique of neutron radiography for fuel cell researches. Water condenses in MEA, GDL and channel in cathode side of PEFC (Polymer Electrolyte Fuel Cell) while PEFC generates electricity. It is expected the condensed water may decrease power generation capability. Visualization of the condensed water behavior is important to study the fuel cell and neutron radiography is effective for the visualization. A borescope system was introduced into neutron radiography to visualize water of thickness in the MEA and the GDL. Borescope system enables neutron radiography to take a picture pixel size of which is 6.5μm and to measure water of thickness in the MEA and the GDL with the exposure time of 50 seconds.

    Hydrogen gas and air are supplied in saturated moist condition to keep a membrane wet in a polymer electrolyte fuel Cell. Condensation may occur in the cathode side, since air is super-saturated by the fuel cell reaction. The condensed water may affect on the fuel cell performance. Water distributions in the operating PEFC were visualized by neutron radiography with measuring the cell voltage. A single cell with an electrode area of 25cm^2 were used in the visualization tests. Dynamic water behaviors were visualized by using neutron image intensifier, and recorded as video images. In order to measure water amount with high resolution, a cooled CCD camera with 16bit intensity levels were used, and still images were recorded. From the still images, water amount in the PEFC could be measured with a spatial resolution of 107μm quantitatively. The correlations between the water distribution and cell voltage fluctuations for three types of separator channels were clearly shown.

    Ushiba Takeshi, Baba Toshiya, Asano Hitoshi, Sugimoto Katsumi, Takenaka Nobuyuki
    This study deals with thermal hydraulic characteristics of a paraffin emulsion, in which a paraffin wax with a melting point of 72℃ and latent heat of 222kJ/kg was used as phase change material. Pressure loss and heat transfer coefficient in a cooling process were measured for a horizontal copper tube with inner diameter of 4mm. As a result, it was shown that heat transfer performance of paraffin emulsion was lower than that of water, because of its high viscosity and a delay in phase change of paraffin wax. Paraffin emulsion at the exit of heating section was in a thermal non-equilibrium condition, and recovery of temperature after mixing was observed.

    This study deals with boiling heat transfer enhancement for a narrow channel by thermal spray coating. Aluminum powder was coated on the heating surface by vacuum plasma spraying. Wall superheats at the onset of boiling and steady condition were evaluated in flow boiling of R123 with inlet subcooling for mass fluxes of 125, 188, and 313kg/(m^2・s), inlet subcooling of 10, 15, and 20, and heat flux 62-365kW/m^2. The test channel with the channel gap of 2mm, channel width of 20mm, and heated length of 100mm was placed vertically and heated on one side by ceramic plate heaters. As the result, it was shown that the coating surface could make wall superheat at the onset of boiling lower and critical heat flux higher than a smooth surface.

  • A Study of Water Hammer Phenomena caused by Steam flow to Drain Piping
    NISHITANI N., FUJII T., ASANO H., SUGIMOTO K., YUMOTO H., NISHIKAWA Y.
    The pressure change and the accompanying fluid vibration occurs due to the water hammer phenomena caused by the steam condensation and sometimes lead to the damage of the pipings. This purpose is to study the water hammer phenomena caused by the steam condensation in a drain pipe. In general, the steam flashed from the steam trap flows into the drain pipe filled with water. In this case, the water hammer phenomena caused by the steam condensation occurs. Here, the steam from a boiler is injected into the drain pipe which is filled with water. The behavior of the steam condensation was taken by the high-speed camera. The correlation between the magnitude of the sudden pressure rise and the size of the steam bubble is investigated.

  • A Study of the Phase Separation Characteristics of Gas-Liquid Two-Phase Flow in T and Y-junction
    FUJII Terushige, ASANO Hitoshi, Sugimoto KATSUMI, HIRANE Masaki
    The purpose of this study is to develop phase separation equipment using a simple impacting T or Y-junction for gas-liquid two-phase flow under microgravity. In order to clarify the effect of tube diameter on the phase separation performance, phase separation experiments in the T (θ=90°) and Y (θ=60°, 30°) junctions of 4 mm ID set in a horizontal plane were carried out using air and water as the working fluids. Moreover, the effect of the flow direction of the inlet flow was evaluated. The phase separation performance was also improved by decreasing of the angle θ between the inlet and the side branch as well as our previous results on junction of 10 mm ID. However, phase separation was not performed for the high gas velocity condition in which the inlet flow regime was an annular flow.

    OHNO Motohiro, FUJII Terushige, ASANO Hitoshi, SUGIMOTO Katsumi
    A two-phase flow thermal control system, which utilizes the latent heat of fluid, is paid attention for the heat romoval in the space station and the Space Solar Power System. The characteristic is that the temperature can be controlled by changing pressure in the accumulator. But a new development of this kind of accumulator is demanded for this system. We proposed the pump-driven type accumulator. As a result of various experiments, it is shown that the pump-driven type accumulator is adequate to change the pressure and the temperature of the two-phase flow loop system.

  • TED-AJ03-169 A Clean Environment Gas Turbine Cogeneration plant :
    SOUFI Mohammed Ghiyath, FUJII Terushige, SUGIMOTO Katsumi
    Factors such as low capital cost, good match of power and heat requirements, and proven reliability can sometimes lead an end user into purchasing gas turbines for use in a modern cogeneration plant. The steam-injected gas turbine is an attractive electrical generating technology for mitigating the impacts of rising energy prices. The technology greatly extends the range of cost-effective gas turbine cogeneration to include many applications that involve variable and unpredictable process steam load. The high efficiency of this technology makes it possible to produce electric power competitively and with low environmental impacts when fired with natural gas and relatively costly synthetic fuels. According to such mentioned above this paper is to provide results of an optimization study on cogeneration power cycle, which works by gas turbine with recuperator and injection steam added to the combustor of the gas turbine (referred to as the Cheng cycle). The performance characteristics of the cycle were investigated. The effect of the recuperator on the cycle was clarified.

  • A Study of the Appraisal Method of Exergy Cost Minimization for Co-generation System
    SUGIMOTO Katsumi, YAMASHITA Tomoya, FUJII Terushige
    Recently, co-generation systems became to be used widespread. However, various kinds of factors such as operational conditions and operation & maintenance cost exist. In this study, the appraisal method of exergy cost minimization for a gas turbine co-generation system is introduced by evaluating the cost for the exergy loss. As the result, if the turbine inlet temperature is increasing, the cost concerning exergy irreversible loss is decreasing. However, the optimum value exists for the exergy cost. The optimum temperature was 1150℃ in the estimation of these values.

    申請者が開発した超音波トモグラフィ法を用いて、ガリウム合金中を上昇する連続気泡を対象に、気泡径、気泡間隔および水平磁場印加時の気泡挙動を実験的に評価することを目的に、研究を実施した。 本年度は試験体系を検討し、連続鋳造で使用されている磁場制御条件も参考に、水平磁場を400mT以上印加するものとした。さらに試験部として、内径50mmの円筒容器とすることで、直径250mm以上の領域において均一な水平磁場を印加可能な電磁石を選定した。液体金属中を上昇する連続気泡にって生じる後流渦の影響を評価するためには、同一の気泡径において異なる気泡離脱周期を実現する気泡発生部が必要となる。そこで、スピーカーを用いた音圧変動を利用することで気泡離脱周期を可変とする気泡注入部を製作し、ガリウム合金への適用性についてX線ラジオグラフィおよび超音波トモグラフィ法で評価した。それにより気泡生成周波数が5Hzまでの条件において、等価径が均一な連続気泡を生成可能であることを確認した。さらに円筒容器において、単一および連続して気泡を上昇させ、断面ボイド分布の連続CT計測を行った。容器底部から20mmの位置を入口条件とし、計測位置140mmの位置において、20mmの位置からのボイド分布の変化を評価することで、気泡離脱周期の違いが及ぼす気泡分散への影響について評価した。更に容器底部に設置した超音波センサを用いて、ドップラ法による速度計測を行った。その結果、磁場強度が弱い条件では、磁場強度を増加させるにつれて気泡上昇速度が増加し、磁場強度を更に増加させると気泡上昇速度が低下することを示した。トモグラフィ計測による結果でも、磁場強度を増加するにつれて、連続する気泡がほぼ同じ計測断面を通過することが示され、気泡通過間隔も一定となることを実験的に示した。

    For a packed bed reactor, which consists of a 1/2-inch stainless steel tube filled with alumina particles having the diameter of 3 mm, the flow behavior of heavy oil in the reactor under the atmosphere of nitrogen gas or supercritical water was observed by neutron radiography. In the heavy oil/nitrogen gas system, the effect of reactor temperature on the flow behavior at atmospheric pressure was clarified. Particularly, the flow channeling was observed in the reactor at a relatively high temperature. In the heavy oil/supercritical water system, the effect of flow rate of heavy oil on the flow behavior was investigated at 400℃ and 25 MPa. Through this work, it was revealed that neutron radiography is a useful technique to visualize the flow behavior of heavy oil in a packed bed reactor, whose wall was made of metal, at high temperature and high pressure.
