Simulation of two-phase flow and mass transfer with deformable interface
Abstract
Two-phase flow and interphase mass transfer are very popular in chemical processes. Rapid development of numerical simulation plays a crucial role in deep understanding of the mechanism of momentum, mass and heat transfer in two-phase systems. However, establishing and solving the mathematical models of two-phase flow and transport processes, especially the accurate description of deformable moving interface, are critical and difficult. This review addresses the level set method and the boundary element method, which are involved with the numerical simulation of two-phase flow of deformable surfaces, and presents a detailed discussion of the limits and advantages of these typical methods. We show the research status and prospect of the mathematical methods of deformation interface of fluid particle coalescence and breakage, micro-fluidics and droplets in two-phase flow field. In the end, we briefly introduce the numerical simulation methods of interphase mass transfer across deformable interface.
