Scale-resolving simulations on unstructured meshes with a low-dissipation low-dispersion scheme

Abstract

This paper presents an assessment of a low-dissipation low-dispersion finite-volume scheme in the DLR-TAU code for scale-resolving simulations on unstructured grids. The scheme is tested in both wall-resolved and wall-modelled LES of the plane channel flow, in pure LES of the periodic 2-D hill flow on a family of grids, and in a hybrid RANS/LES of a generic 3-D Delta wing. Overall, the LD2 scheme is found to yield consistent results and sensitivities for structured and unstructured grids.
