SOLUTAL BOUNDARY CONDITIONS OF MARANGONI CONVECTION IN FLOATING ZONE

There may exist two kinds of solutal boundary conditions, that is, given value of concentration or given flux of concentration at the melting interface for thermal and solutal capillary convection in the floating zone. The solutions of the two kinds of problems are obviously different. In the present paper, the physical processes and their influence associated with these problems of two kinds of boundary conditions have been analyzed.
