Large Eddy Simulation of Rotating Turbulent Convection Using the Subgrid Scale Estimation Model

Abstract

A large eddy simulation with the estimation subgrid scale model was used to simulate rotating convective flows up to a Rayleigh number of 8.4x10(exp 6). The flow fields demonstrated expected qualitative properties of rotating flow including radially oriented convective plumes. The Nusselt number and mean temperature profiles show the decreased mixing due to rotation and agree well with DNS results. For higher Rayleigh numbers, including truncated Navier-Stokes dynamics resulted in better agreement with DNS.
