Abstract
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 incompressible THETA code allows for efficient and accurate mean-flow predictions of a rudimentary landing gear. Thus, the maturity of the applied models and the numerical solvers for flows with massive separation is demonstrated.
