This study deals with the numerical investigation of the flow around a high-lift airfoil with deployed slat and flap, with focus being made on the slat cove region. Two different techniques are used and compared to simulate the unsteady flow around such an airfoil, both being based on a hybrid RANS/LES formulation in order to minimize as much as possible the computational resources. In this paper, a comparison of the results from these two approaches (namely ZDES and NLDE) is presented, both from the statistical and unsteady points of view. The two approaches provide results which are in excellent respective agreement.
