Advanced near-wall Reynolds-stress modelling is applied to the stall of a subsonic flow-through nacelle and a transonic powered engine. For both flows the simulations provide improved predictions of separation onset compared to conventional turbulence models. In the subsonic stall case, mean-flow predictions at very high angles of attack suffer from too low Reynolds-stress levels in the separated region, which can be partly cured by an RSM-based hybrid RANS/LES approach. In the transonic stall cases, industrial coefficients for the inlet distortion are computed in satisfying agreement with measurements.
