Gas bubble behaviour near the crystallization front (CF) is influences by the thermocapillar Marangoni convection as well as distortions in the melt thermal field and hydrodynamic flow due to adjacent phase interface. It has been shown that thermocapillary flow becomes weakened near the CF and the Marangoni force acting on the bubble increases.
