A new low-dissipation low-dispersion second-order scheme is applied to scale-resolving flow simulations using compressible and incompressible unstructured finite volume solvers. In wall-resolved and wall-modeled large-eddy simulations of the plane ch

Numerical stall simulations are challenging in terms of physical models involved, overall computation effort, and the needed efforts for validation. The present paper describes coordinated, fundamental research into new simulation methodologies and t

The Chimera technique for moving grids is used to take into account non-homogeneous unsteady onflow conditions in the simulation of aerodynamic flows. The method is applied to simulate the transport of a large-scale vortex by a mean velocity field ov

We consider the numerical simulation of a generic lateral vortex, that is generated by a rapidly deflected NACA0021 airfoil. We use the SST k-\(\omega \) URANS approach and a hybrid RANS-LES method based on the SST model, where a zonal RANS-LES inter

The fully-developed channel flow at \(Re_\tau \approx 395\) is used to validate scale-resolving simulations with the unstructured compressible DLR-TAU code. In a sensitivity study based on wall-resolved LES a low-dissipative spatial scheme is derived

Different sensors that provide a measure for the resolution of the LES content in hybrid RANS/LES computations are proposed and investigated. In an a-priori test on isotropic turbulence a suitable sensor is identified. Based on that sensor an automat
