Vortex roll-up processes at two different wing tip shapes are investigated using the DLR TAU flow solver in combination with a Reynolds Stress Model. The performance of the SSG/LRR-Reynolds Stress Model is hereby explored. Results from simulations are compared to state-of-the-art eddy-viscosity models as well as experimental results from literature and own investigations. The SSG/LRR-model predicts the mean flow much more accurately than the eddy-viscosity models. However, deviations up tocompared to experiments can be found which are related to an inaccurate prediction of the Reynolds stresses in the inner vortex core.
