LARGE-EDDY SIMULATION OF THE FLOW AROUND A SURFACE-MOUNTED CUBE USING A DYNAMIC ONE-EQUATION SUBGRID MODEL

Resumo

Dynamic one-equation models enable us to predict the reverse transport of turbulent energy. The present paper provides an explanation of this "backscatter" phenomenon. LES was used to study the k equation with the aim of improving RANS models. This work is part of the project entitled "Large Eddy Simulation for Computing the Flow Around Vehicles" (http://www.tfd.chalmers.se/~lada/projects/sinisa/proright.html) in collaboration between the Department of Thermo and Fluid Dynamics at Chalmers and the CFD group at the Volvo Car Corporation.
