The simulation of a jet in cross flow is of prime interest as a broad range of technical applications feature this phenomenon. However, a correct prediction still poses a challenge to modern CFD codes and turbulence models due to inherent complex dynamics and appearance of coherent structures. Jet in cross flow applications in the aeronautical area, such as auxiliary air system exhausts, additionally demand simulation strategies that allow a proper prediction of the flow field even at high Reynolds numbers. As standard statistical turbulence models show deficiencies when applied to this complex flow, a temporal and spatial resolution of turbulent scales is desired. Therefore, the applicability of Scale-Resolving Simulations (SRS) is investigated on a generic jet in cross flow configuration. Different approaches such as solving the Unsteady Reynolds-Averaged Navier-Stokes (URANS) equations as well as employing Scale-Adaptive Simulation (SAS), Delayed Detached Eddy Simulation (DDES) and Embedded Large Eddy Simulation (ELES) are validated against experimental data. Moreover, the analysis of time statistics and the transient flow field in combination with spectral analysis allow a better understanding of inherent dynamics and mixing phenomena.
