Control of thermocapillary convection in a two-layer liquid system
Abstract
This study concentrates on a system that consists of a superposition of two liquid layers. The two technologically most important issues are the prevention of rupture of the liquid layer and the prevention of developments of unsteady convection within the layer. Dynamics of the liquid is dominated by thermocapillary effect in the absence of gravity. It is shown that the system preserves its topology only if the temperature field satisfies certain constraint conditions. The intensity of the convection may be appreciably reduced by properly changing material properties and/or thickness of the top layer.
