Numerical studies were undertaken to assess the consistency of a wind tunnel experiment and of numerical simulations performed to investigate the potential of shock control devices in transonic flow. Behaviour of the shock control bumps under consideration heavily depends on the local flow condition, which on the other hand is considerably influenced by wall interferences experienced in the wind tunnel experiment. The study presented herein uses a CFD-RANS method to numerically model the wind tunnel and simulate the complete channel flow with all relevant interference effects. Comparisons of experimental and numerical results for a clean airfoil mounted in the wind tunnel are presented.
