Abstract

Thermal radiation and melt convection in CZ single crystal growth furnace are extremely complicated and make the model of global analysis of transport phenomena inside the whole growth furnace have been established on axisymmetrical and pseudo-steady assumptions. In this paper a three-dimensional global analysis of heat transfer by considering unsteady three-dimensional melt flow was developed, and the effect of unsteady three-dimensional melt flow was discussed. The results indicate that the predicted critical rotation Reynolds number at which the crystal/melt interface reverses is greatly lowered down close to the practical.
