Abstract
The influence of longitudinal vortices on the high-lift behavior of a generic three-dimensional wing is presented. 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 different angles of attack. For the simulations, the Menter-SST turbulence model is applied. 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. The characteristics of the vortices are described and the influence on the stall mechanism is shown.
