G0600202 浮力・マランゴニ共存対流における流れと温度場に関する研究

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.
