Three dimensional simulations of the horizontal bridgman growth of a gallium arsenide crystal is developed. The computer model solves time-dependent, Navier stokes equations with Boussineq approximation by the finite difference method. A new model of nodal latent heat is adopted for melting and freezing processes. The interface of solid/liquid phases as well as flow and temperature fields of both phases is obtained. The simulations find that the moving speed and applied temperature gradient have impact on the shape of the interface. The radiation heat loss in the process plays a major role in the heat transfer mechanism, which must be considered in order to obtain correct simulation.
