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.

Nyckelord: Subgrid-scale model, SGS model. LES. Large eddy simulation, Backscatter, Surface-mounted cube
