Large-Eddy Simulation of Streamwise Rotating Turbulent Thermal Flows Based on Advanced Subgrid-Scale Models

In this paper, we investigate the effects of Coriolis force on a heated plane channel flow subjected to streamwise system rotations using the method of large-eddy simulation (LES). Numerical simulations were performed using two dynamic subgrid-scale stress models and one dynamic subgrid-scale heat flux model; namely, the conventional dynamic model (DM) and an advanced dynamic nonlinear model (DNM) for closure of the filter momentum equation, and an advanced dynamic full linear tensor thermal diffusivity model (DFLTDM) for closure of the filtered thermal energy equation. In order to validate the LES approach, statistics of resolved turbulence quantities obtained from the LES were thoroughly compared with the available direct numerical simulation (DNS) results.
