Abstract: Abstract The Discontinuous Galerkin method is a high-order method in space reducing the amount of cells needed for calculations compared to standard computational fluid dynamics (CFD) solvers. At the Institue for Aerodynamics and Gas Dynamics the CFD code SUNWinT has been developed using a DG method with the aim to apply it to rotor flows. The present study concerns the progress in simulating the flow phenomena of an isolated rotor in hover. The results of the calculations are compared to experimental data and show good agreement. Furthermore, the first phenomenological results of the flow around an isolated rotor in forward flight are presented, which reveal promising results and should serve as a starting point for future investigations.
