Abstract:

Formation of cyclonic vortex from isolated heat source in a rotating fluid layer was studied experimentally and numerically. It was shown that structure of the vortex strongly depends on main governing parameters such as Grasshof number and Rossby number. PIV measurements were carried out for fluids with different values of Prandtl number (from 40 to 250). Numerical simulations were done using CFD software FlowVision.
