Abstract
Discontinuous Galerkin (DG) methods allow high-order flow solutions
on unstructured or locally refined meshes by increasing the polynomial
degree and using curved instead of straight-sided elements. DG
discretizations with higher polynomial degrees must, however, be
stabilized in the vicinity of discontinuities of flow solutions like shocks.
In this article, we device a consistent
shock-capturing method for the RANS-kw turbulence model
equations based on an artificial viscosity term that depends on
element residual terms. Furthermore, the discontinuous Galerkin
method is combined with a residual-based adaptation algorithm that
targets at resolving all flow features. The higher-order and adaptive
DG method is applied to a fully turbulent transonic flow around the
second Vortex Flow Experiment (VFE-2) configuration.
