Abstract:
Window buffeting is a major source of flow-induced sound and vibration. This paper will describe window-buffeting measurements acquired on a full-scale vehicle as well as two different simplified small-scale models. The experimental data sets included microphone and phase-averaged Particle Image Velocimetry (PIV) measurements both of which show that the flow physics are qualitatively and quantitatively similar in all cases. The implication of this result is that simplified laboratory models of a vehicle are sufficient to study the various aspects of window buffeting in full-scale vehicles.
