Radiation-convective heat transfer from silicon crystals to the environment was investigated with the Chokhralsky method. The systems of equations of thermogravitation and mixed convection in the term vortex, stream function and temperature were solved numerically by the finite element method. The influence of crystal rotation on the spatial forms of convective flows of the surrounding gas and on non-stationary temperature fields in the gas and in the crystals was studied. Calculations were made for crystals of different lengths. The calculations were performed with the Prandtl number equal to 0.68 (argon) and the Grashof number 16000, typical for a real technological process.
