Abstract

For given aspect ratio and given geometry, the nature of Rayleigh Benard convection (RBC) is determined by the Rayleigh number Ra = bg DL3 / (kn)Ra=gL3() and by the Prandtl number Pr = n/ kPr= is the thermal expansion coefficient, g the gravitational acceleration D = Tb - Tt=Tb−Tt the difference between the imposed temperatures Tb and Tt at the bottom and the top of the sample, respectively, and v and k the kinematic viscosity and the thermal diffusivity, respectively. The rotation rate Ω (given in rad/s) is used in the form of the Rossby number Ro = Ö{bg D/ L / (2 W)}Ro=gL(2)
