Abstract
The present paper reports a Large Eddy Simulation (LES) of turbulent combined forced and natural convection between two vertical parallel plates maintained at two different temperatures. For the subgrid-scale (SGS) model, both a Smagorinsky eddy viscosity model (SM) and a dynamic eddy viscosity model (DM) with a constant SGS Prandtl number are investigated. The present predictions indicate that LES using both models capture many important features of this flow, such as the effect of buoyancy on the mean velocity profile. However, the dynamic model gives a better prediction for the temperature field.
