Abstract
In this paper a numerical solution method for the compressible Navier-Stokes (NS) as well as the Reynolds-averaged NS equations, based on the Discontinuous Galerkin (DG) space discretization, is presented. In order to close the Reynolds-averaged Navier-Stokes (RANS) system we use the Spalart-Allmaras or the Wilcox k-ω turbulence model. The paper includes some details of the code implementation. The excellent parallelization characteristics of the scheme are demonstrated, achieved by hiding communication latency behind computation, and some results are shown, like flows past a sphere and a classical airfoil.
