A hybridized discontinuous Galerkin method for turbulent compressible flow

We present a hybridized discontinous Galerkin method for two-dimensional turbulent compressible flow. More precisely, we use the Reynolds-averaged Navier-Stokes equations complemented with the k-ω turbulence model devised by Wilcox [21] and modified by Bassi et al. [5] for high-order methods. By means of hybridization, we can formulate the resulting set of algebraic equations only in terms of the degrees of freedom on the skeleton of the computational mesh, i.e. the element interfaces. As a result, both storage requirements and computational time can be reduced. We discuss several test cases stemming from internal and external aerodynamics. © 2014 by Michael Woopen.
