Abstract

The effects of rotation on the convective heat transfer and flow structuring in a cylindrical volume of fluid is investigated with direct numerical simulation (DNS). A formulation of the discrete equations of motion in cylindrical coordinates is solved with finite-difference approximations. At constant Rayleigh (Ra; dimensionless temperature gradient) and Prandtl (Ro, the ratio of buoyancy and Coriolis forces, is varied between runs with 0.045 Ro ............ For Ro 1.2 we find the so~called large-scale circulation. At Ro 1.2 slender columnar vortical plumes are found. In a range of Ro heat transfer is increased by Ekman pumping in the vortical plumes. plumes.
