Language：English Publishing type：Research paper (scientific journal) Publisher：Experimental Thermal and Fluid Science

Axial development of the base film thickness of an upward air–water annular flow after passing through a 90° bend was investigated. The pipe diameter D of the channel was 5.0 mm. The ratios, R*, of the radius of curvature of a bend to D were 6.0 and 10. The dimensionless axial distances, z* (=z/D), of measurement positions were 4, 12 and 20, where z is the axial coordinate in the vertical section. The circumferential measurement positions, θ, from the outer side to the inner side of the bend at each z* were 0, 45, 90, 135 and 180°. The liquid film thicknesses on the top and bottom sides in the horizontal section were also measured. At z* = 4, the base film at θ = 0° was thicker than that at the other θ in most of the present experimental conditions. In contrast, the circumferential distribution of the base film thickness was symmetric even at z* = 4 in the cases of high gas volumetric flux and low liquid volumetric flux. The circumferential distributions of the base film thicknesses at z* = 12 and 20 were symmetric in all experimental conditions. At z* = 12 and 20, the circumferential averaged base film thickness after passing through the bend with R* = 10 was larger than that after passing through the bend with R* = 6. The axial velocity in the liquid film was also measured. The circumferential distribution of the axial velocity was nearly symmetric at z* = 12 and 20.

Language：English Publishing type：Research paper (scientific journal) Publisher：Microfluidics and Nanofluidics

© 2019, Springer-Verlag GmbH Germany, part of Springer Nature. The pressure difference in gas–liquid Taylor flow in square microchannels with three different hydraulic diameters (190, 298, and 505 μm) were measured. Three liquids (Water and two types of glycerol-water solutions) were used as the liquid phase, and N2 gas was used as the gas phase. The experiments were carried out for the ranges of 1.98 × 10−3 < CaT < 0.132 and 2.61 < ReT < 661, where CaT and ReT are the capillary and Reynolds numbers based on the total volumetric flux, respectively. The measured pressure drop of Taylor bubbles based on the unit cell model was compared with existing models, and large discrepancies could be recognized. Dimensionless pressure drop of a Taylor bubble increased with the capillary number, and depends on the liquid viscosity and the hydraulic diameter at the same capillary number in the middle and high capillary number region, i.e., the inertia effect. Hence, a new pressure drop model including these effects as dimensionless numbers was developed based on the relationship between the pressure drop and liquid film thickness of a Taylor bubble, and it could show good agreement with the measured data. The pressure drop of Taylor flow could also be evaluated using the unit cell model with the developed model. In addition, a pressure drop model for Taylor flow based on only the total volumetric flux was developed in terms of convenience of prediction.

Language：English Publishing type：Research paper (scientific journal) Publisher：Elsevier Participation form：Joint(The vice charge)

© 2017 Elsevier Inc. The void fraction and pressure drop of gas-liquid slug flow in a circular microchannel were measured using a high-speed video camera and image processing method. Water and two types of glycerol-water solutions were used as the liquid phase, and N2 gas was used as the gas phase. Four microchannels with different diameters (200, 320, 500, and 700 μm) were used. The measured data were compared with the existing and newly developed models. The following conclusions were obtained: (1) the pressure drop was predicted using the model proposed by Warnier et al. (2010) with the liquid film thickness model proposed by Han and Shikazono (2009) within ±20%, (2) a distribution parameter model developed in this study can predict the distribution parameter within ±10% and is more reliable than the other models.

Effect of collision and velocity model of lattice Boltzmann model on three-dimensional turbulent flow simulation Reviewed International journal

Yasuda T., Hashimoto T., Tanno I., Tanaka Y., Minagawa H., Morinishi K., Satofuka N.

International Journal of Computational Fluid Dynamics 31 ( 4-5 ) 258 - 268 2017.5

Language：English Publishing type：Research paper (scientific journal) Publisher：Taylor & Francis Participation form：Joint(The vice charge)

© 2017 Informa UK Limited, trading as Taylor & Francis Group. Various collision and velocity models of the lattice Boltzmann model (LBM) were compared to determine their effects on the efficiency of a three-dimensional homogeneous isotropic decaying turbulent flow simulation. We determined that a decrease in the number of velocities, in particular, 13-velocities, which can be used in the quasi-equilibrium lattice Boltzmann and in the multiple-relaxation time models (MRT), could considerably decrease the computational effort. However, decreasing the number of velocities deteriorates the stability and the accuracy of the results. By comparing the collision models, we also determined that the stability of the entropic lattice Boltzmann model (ELBM), and 19- and 27- velocity MRT is much higher than in other models. However, the numerical viscosity introduced by the ELBM underestimates the enstrophy, and the computational effort increases because of the calculation overhead required to solve the additional equations if special care is not given to the calculation.
