Abstract
This paper examines the issues relevant to the interpretation and scaling of data obtained from wind tunnel experiments on flows over cavities. Data from twelve previously published experiments has been extracted and compared. A characteristic of cavity flows is the aeroacoustic resonance that may occur under certain circumstances. Based on the comparison of the existing data sources, the important parameters affecting the observed resonant frequencies are identified and discussed. To provide a framework for the data analysis existing mathematical and physical models of cavity resonance are reviewed. Finally, some of the experimental issues surrounding measurements of aeroacoustic flows are discussed.
