Abstract

We present direct numerical simulation results (DNS) for a compressible mixing layer and a compressible boundary layer on a flat plate in 2D. The exact filtered Navier-Stokes equations are derived and the contribution of the subgrid-terms and the discretisation errors is calculated by filtering the DNS data to a coarser grid. It will be shown that the discretisation errors are larger than the dominant subgrid terms if the filterwidth is comparable to the grid spacing. This holds for second and fourth order accurate spatial discretisations.
