Abstract
We present large-eddy simulation (LES) results of the streamwise-periodic hill channel configuration, which is a standard test case for massively separated flows. The Reynolds number (computed with the hill height, the bulk mass flux through the cross-section above the hill crest and the dynamic viscosity at the wall) is chosen as 2800, in accordance with recent DNS data from Peller & Manhart (2004) for incompressible flow. The Mach number (computed with the volumetric bulk velocity and the wall temperature) was varied between 0.2 and 2.5. The numerical simulation code NSMB discretises the compressible Navier-Stokes equations with the finite-volume method on a deliberately-chosen coarse structured mesh. The subgrid-scales are accounted for by the well-proven approximate-deconvolution model (ADM). Show more
