ABSTRACT

A two dimensional study on the transient natural convection of two stratified miscible liquids inside a cavity is presented. We set out to investigate the motion of the fluids when one wall of the cavity is quickly heated up at a certain temperature, the stratified liquids being initially at rest and in thermal equilibrium. The experiment were done at different inclination angles of the hot wall so that its influence on the dynamics of the process could be observed. Also, several initial concentrations for the denser liquid were tested for each inclination, and the global effect of concentration investigated.
