Natural convection has to be accounted and simulated for in order to properly describe the physics encounter in the phase change process.

A simplified two-dimensional model was created in COMSOL 4.1. Natural convection was accounted for by adding a volume force and using the Boussinesq approach. The heat transfer and laminar flow physics were used. Results showed that natural convection played a noticeable role in determining position and behavior of the solid-liquid interface.
