This work is dedicated to the appropriate representation of the experimental setup in the numerical prediction of the flow around multi-element airfoils. In the simulations a high-fidelity Reynolds-stress RANS-model is applied. The well established Menter-SST RANS-model is used as a reference. To assess the influence of the wind-tunnel walls three different numerical approaches with different computational complexity are compared: A three-dimensional simulation of the entire measurement section, a two-dimensional cut through the centerline of the test section and the same two-dimensional cut but with inviscid wind tunnel walls. The results show that it is sufficient to restrict the simulation to the centerline section of the wind tunnel and treat the wind-tunnel walls as inviscid walls.
