G0600202 Analysis of the Interaction between the Buoyancy Convection and the Marangoni Convection

Abstract

Buoyancy and Marangoni convections were analysed both experimentally and theoretically. We investigated two-dimensional natural convection in a horizontal layer of incompressible fluid. 10 [cs] and 100 [cs] silicone oils were used as the test fluids (1 [cs] = 1×10^<-6> [m^2/s]). The temperature and velocity fields were visualized using liquid crystal capsules. The government equations of buoyancy and Marangoni convections were solved by the finite difference method. The numerical calculation agreed with the experimental result.
