抄録

Free surface deformation and surface oscillation of fluid are the most important physics phenomena in the field of fluid mechanics. In this paper, surface deformation and surface oscillation of the buoyant-thermo capillary convection in a rectangular cavity due to gravity and temperature gradient between the two sidewalls have been investigated. Temperature difference between the two side walls of the cavity is increased gradually, and the flow on the liquid layer will develop from stable convection to un-stable convection. An optical diagnostic system consisting of Michelson interferometer with image processor has been developed, it gives out the displacement of free surface. The present research results demonstrate that surface deformation and surface oscillation are related with temperature gradient and the thickness of liquid layer, it means that they are influenced by both of surface tension and buoyancy.
