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

We present a validation strategy for enhancement of an unstructured industrial finite-volume solver designed for steady RANS problems for large-eddy-type simulation with near-wall modelling of incompressible high Reynolds number flow. Different parts

The viscous flow around a rotating axial fan at a Reynolds number of 9.36 × 10 based on the outer casing diameter is investigated by large-eddy simulation (LES) with special focus on the tip-leakage flow region. A massively parallelized finite-volum

Due to the high cost pressure in the field of aviation, the further increase in effciency is in the focus of development. Nowadays, airfoils are highly developed and optimized. Thus, new sophisticated approaches, additional configurations and physica

Within the present numerical investigation different spherical grooves are applied to a circular cylinder. By the use of the overset grid method a spinning of the cylinder is combined by an in flow from a radial direction to simulate the flow around

There is an increasing interest in flow simulations in configurations where parts are moving relatively to each other. A general approach to this problem is the use of overlapping grids, often called Chimera-technique. An incompressible flow solver b

Scale-resolving simulations of two separated flows using the DLR codes TAU and THETA are presented and compared to reference data. For a tandem cylinder the compressible TAU code is shown to yield equally good results as other flow solvers, and the i

The DLR TAU code is enhanced with the CICSAM method for an algebraic reconstruction of the fluid interface. The incompressible module of the DLR TAU Code is cast in a finite-volume projection method infrastructure for variable density flows. The infr
