Influence of heat transfer at the interface on the thermocapillary convection in the adjacent phase

Thermocapillary convection in a cavity is considered. It is shown that when the cavity, is heated through its sides, reduction of heat transfer across the interface leads to an increase of the interface deformation. When the same cavity is heated through the interface, similar reduction of heat tran, fer across the interface results in diminished convection and reduced interface deformation.
