This paper discusses a CFD procedure for simulating open wind tunnel test sections based on the investigations of the DLR project ForMEx II. Within this project numerical simulations and the analysis of the wind tunnel (w/t) experiments are performed in order to study the potential of CFD to support and improve the w/t corrections. In this paper, the aerodynamic low speed w/t DNW-NWB and the aeroacoustic w/t AWB are investigated. First, computations for the empty test sections are conducted, for the evaluation of the CFD potential to simulate the open jet flow in each of the w/ts, and second, the open jet flow with the DLR F16 2D high-lift model installed, for the aeroacoustic AWB w/t. The overall good agreement of the numerical results compared to the experiments indicate a reliable capability to simulate and further support the development and adjustment of the tunnel corrections for open test sections.
