The flow conditions at the edges of the flight envelope of aircraft configurations has long been a research focus in the authors’ respective working groups. Coupled with the high Reynolds numbers characteristic for aircraft configurations in free flight, such operating conditions pose challenges for experimental and numerical investigations due to complex flow phenomena and large scale unsteadiness. This focus motivated to works in the context of a DFG-funded project, which led to insight into appropriate simulation methods that are capable of reproducing the wake physics. Hybrid RANS/LES methods such as Delayed Detached Eddy Simulation (DDES) emerged as the appropriate method for simulations of this type. The ESWIRP project provided measurement results which were used for validation of such simulation results.
