Three-dimensional simulations of the Czochralski bulk flow

Abstract Six numerical simulations of 3-dimensional time-dependent flow in the presence of a non-axisymmetric temperature distribution at the crucible wall are described. All simulated cases have in common the presence of temperature oscillations and/or time periodic flow. It is also shown that the crucible rotation is needed in order to symmetrize the temperature field in the vicinity of the solid-liquid interface.
