Book excerpt: This experimental study was carried out at a free-stream Mach number of 0.6 and a Reynolds number per foot of 3.45 x 106. The magnitudes of the wall-pressure fluctuations agree with the Lilley-Hodgson theoretical results. Space-time correlations of the wall-pressure fluctuations generally agree with Willmarth's results for longitudinal separation distances. The convection velocity of the fluctuations is found to increase with increasing separation distances, and its significance is explained. Measurements with the longitudinal component of the velocity fluctuations indicate that the contributions to the wall-pressure fluctuations are from two regions, an inner region near the wall and an outer region linked with the intermittency.

Book excerpt: The study of pressure-velocity correlation in turbulent flow was extended to turbulent boundary layer flow over a roughened wall in the absence of a longitudinal pressure gradient. The results obtained are qualitatively similar to those previously measured over smooth walls. A theory is presented to partially explain the behavior of the measured correlations in both the smooth-wall and rough-wall cases.

Mautner and published by . This book was released on 1985 with total page 19 pages. Available in PDF, EPUB and Kindle. Book excerpt: Knowledge of the wall pressure fluctuations beneath transitional and turbulent flows is required in order to understand and reduce aerodynamically and hydrodynamically generated noise. Measurements inside and outside turbulent boundary layers indicate that the wall pressure fluctuations generated by turbulence may well be the dominant mechanism in the generation of near field noise (self-noise) and, if the wall pressure fluctuations are coupled with the vibratory modes of the structure, there will be a significant increase in the sound level radiated into the far field. Wall pressure fluctuations were measured in the plane of symmetry of turbulent spots convecting in a laminar boundary layer having zero, favorable and adverse pressure gradients. The results show that the magnitude of the rms(root mean square) wall pressure and the spectra of the turbulent spot phase of boundary layer transition are strongly influenced by the local mean flow pressure gradient. The data also verifies that boundary layer transition in the presence of an adverse pressure gradient produces rms wall pressure fluctuations which are 1.5-2.5 times larger than those found in either a zero or favorable pressure gradient. Keywords: Acoustic efficiency, Wall pressure fluctuations; Turbulent boundary layers; Artificially generated turbulent spots.

This book was released on 1977 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: A buoyancy propelled, fin-stabilized vehicle with a favorable pressure gradient over a major portion of its length was tested at Lake Pend Oreille, Idaho. Turbulent boundary layer wall-pressure fluctuations were measured at numerous locations of the body. In the region of favorable pressure gradient, the normalized wall-pressure spectral density was found to be similar to that on a flat plate. Transition from laminar to turbulent boundary layer flow occurred on the 30-inch-maximum diameter vehicle at transition-length Reynolds numbers as large as 9.2 million. (Author).
