InVIGO will present results during 3AF 2020+1 congress in April 2021. Results regarding ground vortex on both isolated nacelle and wind tunnel configuration will be compared.

The paper is a common Altran/CSTB article and will describe the experimental set-up in addition with numerical results. Similar ground vortex results are obtained for the chosen operating point. Several vortex post-processing strategies are investigated to get consistent results in both steady and unsteady (Hybrid RANS/LES) simulations.
