Kurzfassung
In the present work, topology induced uncertainties on grids for finite volume methods with the focus on the wake region are investigated. Analysis shows, that the grid resolution in the wake region has a notable influence on the flow solution and thus on the aerodynamic coefficients. To allow a local adaptation of hexahedral grid parts for the DLR–TAU–Code, a refinement method for hexahedra is presented here. In 2D, the method is applied to the wake of the low–speed NLF(0)–416 airfoil, whereas in 3D it is applied to the high–speed wing ONERA–M6 as well as a low–speed flow–through nacelle. In all presented test cases, a notable effect of the local adaptation is observed.
