• Shapes of surfactant-laden Taylor bubbles in a square microchannel

  Ryota Igarashi, Riku Hachikubo, Ryo Kurimoto, Kosuke Hayashi

  Abstract Experiments on contaminated Taylor flows in a square microchannel were carried out to investigate the effects of surfactant on the bubble shape in the nose and tail regions for different surfactant properties. The nose curvature was found to be proportional to the bubble length at low surfactant concentrations, while it was independent of the concentration at high concentrations. The rate of increase in the nose curvature at the former concentrations can be expressed in terms of the surface coverage ratio. The bubble velocity decreased with increasing the nose curvature, whereas the surface tension reduced by surfactant adsorption worked better to correlate the velocity data. The curvature of the bubble tail increased steeply at low concentrations as a consequence of the early coverage due to interfacial advection. The tail curvature also had a strong correlation with the surface coverage ratio.

• Pressure drop and bubble velocity in Taylor flow through square microchannel

  Ryo Kurimoto, Kosuke Hayashi, Akio Tomiyama

  Abstract Interface tracking simulations of gas–liquid Taylor flow in horizontal square microchannels were carried out to understand the relation between the pressure drop in the bubble part and the curvatures at the nose and tail of a bubble. Numerical conditions ranged for 0.00159 ≤ Ca_T ≤ 0.0989, 0.0817 ≤ We_T ≤ 25.4, and 8.33 ≤ Re_T ≤ 791, where Ca_T, We_T, and Re_T are the capillary, Weber, and Reynolds numbers based on the total volumetric flux. The dimensionless pressure drop in the bubble part increased with increasing the capillary number and the Weber number. The curvature at the nose of a bubble increased and that at the tail of a bubble decreased as the capillary number increased. The variation of the curvature at the tail of a bubble was more remarkable than that at the nose of a bubble due to the increase in the Weber number, which was the main cause of large pressure drop in the bubble part at the same capillary number. The relation between the bubble velocity and the total volumetric flux was also discussed. The distribution parameter of the drift-flux model without inertial effects showed a simple relation with the capillary number. A correlation of the distribution parameter, which is expressed in terms of the capillary number and the Weber number, was developed and was confirmed to give good predictions of the bubble velocity.

• Effects of Microbubbles on Germination and Growth of Spinach

  MINAGAWA Hisato, FUJIWARA Kai, KURIMOTO Ryo, YASUDA Takahiro, HARADA Emiko, HATA Naoki

  Effects of microbubbles on germination and growth in deep flow technique of spinach (Spinacia oleracea) were investigated. In the germination experiment, four experiment plots; (1) underwater germination with microbubble water plot (MB plot), (2) underwater germination with aerated water plot (Aeration plot), (3) underwater germination with water plot (Water plot), (4) germination on wet cotton plot (Control plot), were used. Two hundred individuals were germinated for each plot. Germination rate of MB plot after 7 days was about twice as high as that of Aeration plot and Control plot. In the growth experiment, three experiment plots; (1) tenth solution concentration water with microbubble plot (MB plot), (2) tenth solution concentration water plot (Aeration plot), (3) full solution concentration water plot (Control plot), were used. Twelve individuals were grown for each plot. Leaves weight of MB plot was as much as that of Control plot. In contrast, plant physiological disorders appeared in all plants of Aeration plot. Multi-element determination revealed that K concentration of Aeration plot was lower than that of the others plots. These results indicate that microbubbles contribute to the plants absorbing the nutrient from roots.

• Interface Tracking Simulation of Drops Rising through Liquids in a Vertical Pipe Using Three Coordinate Systems

  Kosuke Hayashi, Ryo Kurimoto, Akio Tomiyama

  Interface tracking simulations of single drops rising through a vertical pipe are carried out using three coordinate systems, i.e. cylindrical, general curvilinear and Cartesian coordinates, to investigate the effects of coordinate system and spatial resolution on the accuracy of predictions. Experiments of single drops in a vertical pipe are also conducted to obtain experimental data for comparisons with simulations. The drop shape observed are spheroidal and deformed spheroidal at low values of the diameter ratio, Λ, of the sphere-volume equivalent diameter of a drop to the pipe diameter, whereas they take bullet-shapes at large Λ. The conclusions obtained are as follows: (1) the effects of coordinate system on drop shape are small at low Λ. At large Λ, the effects are also small for drops in a low viscosity system, whereas non-physical shape distortion takes place when the Cartesian coordinates are used with low spatial resolution for drops in a high viscosity system, and (2) the drop terminal velocity and the velocity profile in the liquid film between a bullet-shaped drop and a pipe wall are well predicted using all the coordinate systems tested even at low spatial resolution.

  Numerical simulation would be useful for design and development of membrane bioreactors (MBR) in the view of visualization and prediction of flow in MBR plants. Experimental data on a relation between motion of membraned and bubbly flow are lacking, although motion of membranes should be implemented in the numerical simulation. We carried out experiments to observe bubbly flow, measure removal rate of a sludge and evaluate motion of membranes in an experimental setup with hollow fiber membranes. Liquid property affects bubble break-up at a lower tie plate and membranes. Liquid property affects the number of bubbles and those diameter in bubbly flows, since frequency of bubble break-up occurring at lower tie plate and membranes varies. This variation of the structure of bubbly flows affects removal rate attached to sludge.
