Assessment of Split Form Nodal Discontinuous Galerkin Schemes for the LES of a Low Pressure Turbine Profile

Abstract

Due to the favorable dispersion and dissipation characteristics combined with local data and algorithm structures on unstructured grids, the discontinuous Galerkin (DG) method is a promising candidate for scale-resolving simulations of turbomachinery flows, c.f. [5]. Especially the dissipation characteristic of the upwind DG operator is an interesting aspect for large eddy simulation (LES) as it affects only the largest wave numbers and leaves lower and medium wave numbers uninfluenced.
