High-lift configurations are often a challenge for numerical simulation once it comes to the prediction of maximum lift. This is not so much a problem of the separated flowin the wing and slat coves, which are rather confined, but of the pressure induced separation taking place on the upper flap surface.With respect to a Scale-Resolving Simulation (SRS) this kind of separation is certainly prone to the grey area issue, while due to the recirculation of turbulent eddies the cove flowis mainly treatable by standard SRS approaches like DDES. Other important aspects in the frame of SRS and the grey area are the shear layers leaving the trailing edges of all airfoil elements contributing to noise (especially in the case of the slat) and themixing of shear layers with wakes. As all these interactions together determine the global flow pattern (i.e., lift and drag), every single aspect has to be treated correctly to arrive at accurate flow and sound predictions of such high-lift configurations.
