Abstract
A review of recent progress in numerical simulation of vortex-flow aerodynamics at the Institute for Design Aerodynamics of the DLR-Braunschweig is presented. The paper is devoted to the prediction of vortex lift including vortex breakdown, vortex-vortex interaction and shock-vortex interaction. Results are obtained both for compressible and incompressible flow using the DLR Euler/Navier-Stokes CEVCATS-RANS solver. Emphasis is placed on the accuracy limits and ranges of applicability of both Euler and Navier-Stokes calculations for design applications. Computed solutions are correlated with available experimental data for generic but representative geometries of delta wings with and without strake and canard. The results provide an added measure of confidence in the computational solutions of both Euler and Navier-Stokes equations for vortical flows and they also point out some of the limitations.
