Abstract
Results from large eddy simulations of the wake vortex behaviour in ground effect with turbulent crosswinds are presented. We have conducted wall-resolved and wall-modelled simulations at different Reynolds numbers to investigate the Reynolds-number dependency. Vortex displacement and decay has been validated with experimental data. In order to understand wake vortex decay mechanisms in ground proximity the interaction of primary and secondary vortices is thoroughly investigated. Obstacles at the ground surface are introduced to trigger rapid vortex decay.
