Kurzfassung
The fully-developed channel flow at Re_tau ≈ 395 is used to validate scale-resolving simulations with the unstructured compressible DLR-TAU code. In a sensitivity study based on wall-resolved LES a low-dissipative spatial scheme is derived, which allows to predict the channel flow in fair agreement with DNS. Then the scheme is used in Improved Delayed DES computations in order to assess TAU’s capabilities for wall-modelled LES. Spatial-resolution requirements for obtaining acceptable mean-flow results are pointed out in a grid study. Besides, the combination of IDDES with an advanced vorticity filter is verified, and the effect of the underlying RANS approach, including Reynolds-stress modelling, is analysed.
