Influence of gravitational and vibrational convection on the heat and mass transfer in the melt during crystal growth by the bridgman and floating zone methods

Abstract

A comparative analysis of hydrodynamic and thermal processes during crystal growth by the Bridgman and floating zone methods under terrestrial conditions and in microgravity is performed by mathematical simulation. Specific features of the hydrodynamic state of the melt under axial vibrational perturbations of different frequency and intensity are studied. It is shown that the floating zone method is less sensitive to the Rayleigh–Taylor instability of a liquid-phase flow.
