Kurzfassung
The numerical modeling of airfoil oscillations in wind tunnels is investigated on the basis of frequency response functions of the flow field due to a forced motion input employing unsteady RANS simulations. The analyzed models rea sonably predict the unsteady wind-tunnel wall effects, including the acoustic wind tunnel resonance. For high frequencies, however, the model shows significant spurious fluctuations related to non-physical reflections at the outflow boundary. Therefore, both increasing the distance to the computational boundaries and a nominally less-reflective boundary condition according to Hedstrom (1979, J. Comput. Phys. 30:222–237) are examined leading to slightly improved results.
