Effect of heat transfer mode on the temperature and thermal stress fields in single crystals

Abstract

Different modes of conjugate heat transfer in a crystal environment–growth chamber walls system with geometry similar to the upper part of a Czochralski thermal unit are investigated numerically. Calculations are performed for an argon Prandtl number of 0.68 and a Grashof number of 16000. The thermal stress fields in the crystal are calculated using the resulting temperature fields.
