Vortex roll-up processes of different generic wingtip shapes are investigated using the DLR TAU flow solver in combination with a Reynolds Stress Model. In contrast to a non-rounded layout an elliptical rounding of the wingtip planform leads to multiple vortices at the wingtip and results in an axial velocity deficit in the vortex core further downstream.
