Abstract: Conjugate heat transfer during growth of multisilicon crystals in flat crucibles by the Bridgman–Stockbarger method is studied numerically. Nonstationary equations of convective heat transfer in the region occupied by molten silicon and the heat-conduction equations for the solidified silicon mass and the walls of the graphite crucible of regular cylindrical shape are solved taking into account the heat of the phase transition. A comparison is made of the crystallization processes in the transient heat conduction mode and in the mode of thermogravitational convection.

Keywords: silicon, crystal growth from melt, Bridgman–Stockbarger method, conjugate convective heat transfer, accounting for the heat of phase transition, numerical simulation, finite-element method.
