Abstract

A technique of solving multi-mode heat transfer problems in semi transpar- ent, phase changing medium is addressed. Simultaneous heat conduction, free and forced convection, radiation and change of phase during Czochralski crystal growth process are modeled. Heat conduction/convection problem is solved using a commercial code based on the Finite Volume Method with the enthalpy technique applied to capture the moving boundary problem. The model of energy, mass and momentum transfer in the melt encom- passes both the forced and natural convection. The problem of radiation is solved using the an in-home code based on the boundary element method. Spectral dependent propert
