Abstract

Abstract

The transport process and flow structure near an evaporating meniscus are highly complicated due to various coupling factors. A numerical model was developed to describe the physical process and motion of a micro-particle near an evaporating meniscus. The evaporation and its cooling effect on the interface, vapor diffusion in the gas domain, as well as thermocapillary flow were considered together with computational fluid dynamics (CFD). At the same time, the particle’s motion was tracked with discrete element method (DEM). The interaction between the micro flow field and the particle, including drag force and buoyancy force, was considered. The simulation results agree well with the experiments in previous published literatures.
