Abstract

A non-mechanical stirring of a melt induced by the heat field rotating around a cylindrical crucible has been studied. Various regimes of azimuthal flows in a liquid were shown to be present under certain conditions. The obtained results would allow one to improve the control over heat-mass-transfer processes under the crystal growth. 1 Introduction The control over heat-mass-transfer processes is very important under the growth of crystals by various methods. Traditionally this control is achieved by contact techniques implying the contact of a physical body and crystallization medium: rotating crystal and/or crucible in Czochralski configuration, accelerated crucible rotation in ACRT-method or the action of partitions, mixers and so on [1]. The contact-free methods of crystal growth h
