Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was undertaken to examine the effect of cavity depth and yaw angle on flow oscillations that occur in an open cavity placed within a subsonic boundary layer. A rectangular cavity was placed within a thick turbulent boundary layer with a corresponding Reynolds number based on the cavity length of 61,935. Pressure time histories were acquired at five separate cavity depths (or L/D values) at each yaw angle from 5 degree to 90 degree using microphone-type pressure transducers. The spectral character of these signals was analyzed, and pressure level and dominant frequencies were determined. This study indicates that large changes in the pressure level occur as L/D varies from 0.5 to 2.1 and as the yaw angle varies from 5 to 90 deg. Relative sound pressure level calculations indicate that the energy within the cavity compared with that of the boundary layer was observed to increase by approximately 22 percent at L/D=2.1 and 2.2 times at yaw angle=60 deg.

This book was released on 2018-11-06 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental investigation was conducted to determine cavity flow-characteristics at subsonic and transonic speeds. A rectangular box cavity was tested in the Langley 8-Foot Transonic Pressure Tunnel at Mach numbers from 0.20 to 0.95 at a unit Reynolds number of approximately 3 x 10(exp 6) per foot. The boundary layer approaching the cavity was turbulent. Cavities were tested over a range of length-to-depth ratios (l/h) of 1 to 17.5 for cavity width-to-depth ratios of 1, 4, 8, and 16. Fluctuating- and static-pressure data in the cavity were obtained; however, only static-pressure data is analyzed. The boundaries between the flow regimes based on cavity length-to-depth ratio were determined. The change to transitional flow from open flow occurs at l/h at approximately 6-8 however, the change from transitional- to closed-cavity flow occurred over a wide range of l/h and was dependent on Mach number and cavity configuration. The change from closed to open flow as found to occur gradually. The effect of changing cavity dimensions showed that if the vlaue of l/h was kept fixed but the cavity width was decreased or cavity height was increased, the cavity pressure distribution tended more toward a more closed flow distribution.
