Kurzfassung
This work is dedicated to the resolution requirements of Large-Eddy Simulation (LES) with near-wall modelling for attached and massively separated flows at high Reynolds numbers using the DLR THETA code. Two sensors are proposed to measure the resolution quality of LES for statistically steady flows. The first sensor is based on the resolved turbulent kinetic energy and the second one considers the resolved turbulent shear stress. These sensors are applied to turbulent channel flow at Re_tau=4800 and to the flow over a backward-facing step at Re_h=37500 on successively refined meshes, and results are compared with a convergence study of the mean velocity profiles.
