COMSOL Multiphysics is offering an important alternative to home codes for modeling and simulation of complex problems with including coupled effects on heat and mass transfer. The present work focuses on low Prandtl number fluid melts subject to symmetry breaking and transition to unsteady regimes. These configurations are for practical interest in crystal growth industry, namely the Bridgman configuration is widely used to produce single crystals of compound semiconductors: 2D enclosures provide a basic model for studying hydrodynamic regime occurring on such processes. A first step in this work is to study the effect of magnetic field on liquid metal flow and heat transfer occurring in an annular cavity.
