This work is dedicated to the investigation of the resolution requirements for hybrid RANS/LES simulations for aerodynamic flows at high-lift. First, results of a local DDES for a limited section of a highlift wing with deployed slats and flaps of a full-aircraft configuration are presented. Based on the resolution of this simulation the computational effort for a hybrid RANS/LES simulation of the complete high-lift wing is estimated. Since this estimate results in prohibitively high costs, the focus is shifted to the scale-resolving simulation of a quasi two-dimensional segment of a three-element wing for the further investigations. Three approaches, a zonal DDES, a global DDES and an IDDES, are presented and the last one is evaluated with respect to the resolution of the boundary layers as well as the free shear layers.
