Full text not available from this repository.


The influence of longitudinal vortices on the high-lift behavior of a generic three-dimensional configuration is presented. A simplified vortex system originates at a spanwise slat cut off. The vortex system passes along the suction side of the wing and influences the high-lift and stall behavior. A grid convergence study is performed for the two-dimensional high-lift airfoil and different grid topologies are discussed. Numerical simulations are performed with the DLR TAU code at dif- ferent angles of attack. For the simulations, the Menter-SST turbulence model is applied. The vortex behavior is characterized and the influence on the stall mecha- nism is shown.
