“…Hence, numerical smearing of vortices due to tetrahedral cells is minimized using equally spaced hexahedral cells. An improvement of capturing the behavior of vortices using a hexahedral box has already been shown by Eliasson et al [4].…”

“…Aiming at a better understanding of the complex vortex behavior, numerous experimental and numerical investigations have been performed in various research projects. Important contributions in this area of research are provided within the European projects EUROLIFT and EUROLIFT II [4]- [8]. These projects include extensive numerical and experimental studies of different high-lift configurations with different levels of complexity, which provides a deep understanding of the influence of different components on the lift and drag behavior.…”

This contribution presents results of numerical simulations on a generic high-lift configuration. Properties of the computational grid are briefly described. The numerical simulations are performed with the DLR-TAU-Code at different angles of attack up to stall. The Menter-SST eddy viscosity turbulence model and the JHh-v2 Reynolds-Stress-Model are applied. Streamwise vortices arise at the edge of a slat, which is cut off in spanwise direction, and the corresponding edge of the clean nose. These vortices interact with the flow along the suction side of the wing. While proceeding downstream, a strong interaction between the vortices is observed for high angles of attack. The behavior of the vortex system and the influence on the high-lift performance of the configuration is characterized. In particular, the effect of the applied turbulence models of different types on the prediction of the vortex behavior is shown within this contribution.

“…Consequently CFD code validation represents a major focus of the projects. In addition to the analysis of complex 3D high lift configurations major areas of research cover the fields of improvements of numerical and experimental tools 2,3 , transition prediction 4 , and numerical optimization of high lift devices 5 . An overview about both projects and related literature can be found in Ref.…”
