Comparison of Two One-Equation Subgrid Models in Recirculating Flows
Paper i proceeding, 1999

The present paper presents a comparison of two one-equation models in recirculating flows. Special attention is given to their ability to predict the reverse transport of turbulent energy ('backscatter'). This work is part of the project ``Large Eddy Simulation for Computing the Flow Around Vehicles'' ( in collaboration between the Department of Thermo and Fluid Dynamics at Chalmers and the CFD group at Volvo Car Corporation.
