NUMERICAL STUDIES IN EMBEDDED WM-LES COMPUTATIONS OF THETRANSONIC SHOCK BUFFET ON AN XRF1-AIRCRAFT CONFIGURATION

Transonic flows around transport aircraft configurations may exhibit complex flow phenomena such as transonic shock buffet. In such a case, distinct oscillations of shocks with flow separation arise, which significantly influence the aerodynamics and thus eventually also flight safety. In this work, we resolved the turbulence of shock - boundary layer interaction of selected shocks at the lower wing surface with a novel wall modelled LES method based on Reynolds-Stress modelling.
