In this project we are using the discontinuous Galerkin method for the discretisation of the Navier-Stokes equations for the simulation of unsteady flow problems. In comparison to standard finite volume methods the method is characterised by using a polynomial basis function for the distribution of the solution variables within the cell, so it is possible to use the method with a high-order by increasing the degree of the polynomial function. The method works for structured as well as unstructured cells which suits it even for complex geometries. For turbulence modeling different strategies like hybrid RANS-LES techniques as well as LES models are employed. Here we will focus our work on the further development of these methods for high-order discretisations and validate them on technically relevant test cases.
