In this work a systematic analysis of the simulation of turbulent flows with the Lattice Boltzmann Method is shown.So far, no analysis has pointed out, which closure for the collision term is most suitable for the simulation of turbulent flows. With respect to turbulence modeling in the LES framework, it is of essential interest to validate different collision models to obtain the correct balance between stability and accuracy. On the basis of these findings a novel subgrid-scale closure will be derived.
