Numerical Simulation of Multiphase Reactors with Continuous Liquid Phase

Chapter 2

Fluid flow and mass transfer on particle scale

Abstract

A single particle (bubble, drop, or solid particle) in an infinite continuous phase is a simplified model used to probe the law of multiphase flow and transport processes in complex multiphase systems, and it has been studied extensively by both experimental and numerical simulation. Interfacial instability such as the Marangoni effect on a sub-drop scale, which plays a significant role in heat and mass transfer, is being approached numerically with encouraging success. Different numerical methods, such as orthogonal boundary-fitted coordinate system-based simulation and the level set method, are adopted to simulate the motion and interphase mass transfer of a drop or a bubble ...
