Simulation of LIDAR Wake Vortex Measurements in a Hybrid RANS/LES Framework for Aircraft Landings

Kurzfassung

As a consequence of the growth in the number of flights per year, the airspace in the future is reaching the maximum number of take-offs and landings on the airports. In ground proximity, the main risk for aircraft are the trailing vortices, also called wake vortices. The complex wake structures in the aircraft’s near-field roll-up to a vortex system of two counter rotating vortices further downstream. In order to avoid this risk, minimum separation between landing aircraft must be ensured. This thesis investigates wake vortices of landing aircraft, by the combination of Computational Fluid Dynamics (CFD) and Light Detection and Ranging (LiDAR) measurements.
