Coupled Heat Transfer and Fluid Dynamics Modeling of InSb Solidification

摘要

A method for the directional solidification of melted InSb in a silica ampoule is presented and solved with COMSOL Multiphysics. The configuration and initial boundary settings of the model resemble those used in a de‐wetting vertical Bridgman configuration [1]. A slightly modified version of the method presented by Voller and Prakash [2] is used to account for solidification of the liquid phase, including convection and conduction heat transfer with mushy region phase change. Axial‐symmetric numerical simulations of temperature and velocity fields, under normal gravity, are carried out using different thermal conditions.
