微通道内液-液多相流数值模拟研究进展
Progress in numerical simulation of multiphase flow in microchannels
摘要
Abstract
Droplet-based microfluidic has promising prospects in chemical engineering and biomedicine.Liquid-liquid multiphase flow is the most common flow condition in microchannels,which is relevant in control of droplet dynamics.Thorough research on characteristics of the fluid dynamics is essential in the design of optimized microfluidic devices.A comprehensive review of numerical methods commonly used is presented in this paper.Classified by continuum approaches and lattice-Boltzmann approaches,recent progresses in numerical simulations of liquid-liquid multiphase flow in microchannels are covered.The interface tracking and interface capturing methods are particularly discussed and various numerical models based on the two schemes are introduced.The applications of popular models and numerical results are reviewed with comparisons of their advantages and limitations.The conclusions could be an effective theoretical support for hydrodynamics of interface behaviors in microscale.In addition,multi phase flow coupled with complex interactions of the interface is involved in microchannels,the mechanisms of many phenomenons are still waiting to be revealed.And more accurate description of the interface and the fluid dynamics based on models that require less computation cost is the tendency of numerical simulation on fluid flow in microchannels.关键词
