T型微通道内液-液两相流流型研究
Study on Liquid-Liquid Two-Phase Flow Patterns in a T-Shaped Microchannel
摘要
Abstract
A theoretical model of liquid-liquid two-phase flow in a T-shaped microchannel was developed and numerically analyzed by Lattice Boltzmann method to investigate liquid-liquid two-phase flow regimes and affecting factors. The theoretical model was verified using experimental data available in literature. The results indicate that the flow patterns of liquid-liquid flow are dependent on the flow rate ratio of the two inlets and Weber number of the dispersed phase in a T-shaped microchannel. Three typical flow patterns in a T-shaped microchannel including droplet flow, jet flow and parallel flow are obtained by varying flow rate ratio and Weber number of the dispersed phase. The relative length of the dispersed phase is obviously affected by the capillary number of the continuous phase. When the capillary number of the continuous phase is relatively large, the dispersed phase forms droplets, and the relative length of dispersed phase decreases monotonously with the increase of the capillary number of the continuous phase.关键词
