Abstract : Wall interference research is directed toward increased prediction accuracy, particularly for ventilated tunnels operating at transonic conditions; development of interference assessment techniques from model and/or tunnel boundary measurement; and interference avoidance via various adaptive wall schemes. In addition, since wall interference cannot be separated readily from the effects of other inherent tunnel and test properties such as wall boundary layers, noise, turbulence, model fidelity, etc., some research is being conducted to quantify the effect of other phenomena in order to verify the wall interference effects once they are identified. While there are many outstanding issues still to be resolved, a final solution to the wind tunnel interference problem does appear achievable.
