The effects of inlet vortices on engines operating near the ground have been studied for more than 50 years, but without much focus on the trailing vortices. Computational fluid dynamics is used, on a DLR-F6 modified nacelle, to allow a more detailed look into the trailing vortices. The different trailing vortex components and regimes are presented, and the inlet vortices circulation is calculated inside and outside the engine inlet for these different regimes. The trailing and ground vortex interaction region is shown.
