Excitation of Cavity Resonance by Air Flow
The Journal of the Acoustical Society of America, 1957The excitation of cavity resonance by air flow past the aperture has been experimentally investigated. Rectangular apertures of different aspect ratios were located in the ceiling of a wind tunnel. A large wooden box whose volume could be changed was mounted above to provide the cavity. Intensity levels and frequency spectra were observed as a function

Effect of air cavity on the annular drum
The Journal of the Acoustical Society of America, 1982The effect of the compressibility of the entrapped air on the eigenfrequencies of vibration of the radially symmetric modes of an annular drum with an enclosed air cavity is computed. The frequencies become raised, with the fundamental being most affected, so that the ratios of frequencies of higher modes to first-mode frequency are decreased.

Stability of Air Cavities in Tip Vortices
1996A model is presented to interpret the behavior of air cavities formed in the tip vortex issued from hydrofoils in a water tunnel, when air is injected. These cavities have the ability to move upstream and reach a stable position near the hydrofoil.
