A complete mathematical model has been developed together with an accompanying computer code for the numerical prediction of steady, viscous, laminar, incompressible flows with strong heat conduction, magnetic field effects (ponderomotive forces and Joule heating), latent heat of phase change, and thermal buoyancy. The code is capable of simultaneously predicting fluid flow field and the solidifying regions resulting from strong localized wall cooling. The formulation allows for temperature dependance of physical properties and utilizes Boussinesq approximation for thermal buoyancy. Numerical results for solidification of a silicon melt in a closed container demonstrate the influence of strong magnetic fields on the thermal buoyancy flow and consequently on the liquid/solid interface shape.
