Abstract

The influence of latent heat and natural convection in the melt and the shape of the melt-crystal interface are analyzed for a vertical Bridgman crystal growth system by direct numerical simulation. The temperature and the velocity field in the melt and in the crystal are computed using an homog- enization technique. Initially the ampoule contains poly-crystal material, these container is translated inside a furnace which includes two heating zones characterized by two temperatures which are respectively greater and lower than the melted temperature of the material. The two heating zones in the furnace are separated by an adiabatic zone when the solid-liquid phase change occur. The control of the solidifica
