In computational fluid dynamics, high-order methods have reached a certain level of maturity for the solution of the single-phase Navier-Stokes-Fourier equations. Their main advantages and preferred application areas lie in the field of unsteady multiscale problems, of which turbulence is a prime example. For these types of problems, especially for Large Eddy Simulation at moderate Reynolds numbers, high-order schemes have proven to be effective and efficient alternatives to more traditional numerical schemes. The current project is an extension and continuation of the research conducted in the Numeric Research Group. In this project, the existing codebase of our in-house solver FLEXI will be extended and applied to other computationally intensive problems of engineering interest like particle-laden flow, compressible LES or the incorporation of machine learning techniques. The results are also validated and compared to the state-of-the-art INCA code, which is based on the FV method.
