title = "DNS of convective heat transfer in a rotating cylinder",

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 (s; characterises diffusive properties of the fluid) numbers, the Rossby number Ro, the ratio of buoyancy and Coriolis forces, is varied between runs with 0. 045 = Ro = 8. 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.",
