SINOPSIS

In the present paper a problem on combined thermo-solutal buoyancy forces driven flow in Pb-10wt%Sn semiconductor system filled in a rectangular enclosure has been investigated by numerical simulation. Continuum model for solidification modeling is used.
Generated flow under thermal and solutal buoyancy forces is laminar but could be, under an increase in the thermal gradient, turbulent or transition to turbulent in nature.
External forces such Lorentz force (due to applied magnetic field) are recommended for controlling and stabilizing the flow.
Knowledge of interaction among these forces is important to study the effect of flow on heat rate related to the melt.
