Abstract

Large Eddy Simulation (LES) of turbulent flow forms a field of intensive research. Whereas a Direct Numerical Simulation (DNS) solves all scales present in the flow, LES solves only the large scales directly and models the effect of the small scales, represented by the turbulent stress, with a subgrid-model. For testing subgrid-models two approaches can be distinguished, a priori tests and a posteriori tests. In this paper we will focus on a posteriori tests, in which actual Large Eddy Simulations are performed and the results are compared with results from filtered DNS-data. The flow we consider is the temporal mixing layer at low Mach number. Models incorporated into the tests are: the Smagorinsky model [1], the gradient model [2], the similarity model [3], the dynamic eddy-viscosity model [4] and the dynamic mixed model [5].
