Book Synopsis Wind-tunnel Measurements of Surface-pressure Fluctuations at Mach Numbers of 1.6, 2.0, and 2.5 Using 12 Different Transducers by : Thomas L. Lewis

This book was released on 1972 with total page 60 pages. Available in PDF, EPUB and Kindle. Book excerpt: The turbulent boundary layer on the wall of a 9 by 7 foot wind tunnel was measured with 12 different transducers at Mach numbers of 1.6, 2.0, and 2.5. The results indicated that the wall surface-pressure-fluctuation field was more homogeneous at a Mach number of 2.5 than at Mach numbers of 1.6 or 2.0. A comparison of power-spectral-density data at Mach 2.5 with a summary of similar data (Mach 0.1 to 3.45) showed good agreement. The measurement uncertainty was greatest when frequencies were low and the surface-pressure-fluctuation field was homogeneous. The uncertainty at higher frequencies increased as the surface-pressure-fluctuation field became more inhomogeneous. Since transducer mounting effects and system noise levels were determined not to have contributed appreciably to measurement uncertainties, the result was attributed to an interaction between the surface-pressure-fluctuation field and the transducers. Corcos' correction for size effects improved the comparison between transducers at the high frequencies, but did not eliminate an apparent size effect at the lower frequencies.

Available in PDF, EPUB and Kindle. Book excerpt: Investigations of the pressure fluctuations under a turbulent boundary layer, and the resultant vibration of simple panels, were extended to consider the vibration of stringer-panel arrays and the intermittent pressure field in the boundary layer transition region. The response of multi-panel arrays to turbulent boundary layer excitation was measured for a flow speed of 320 ft./sec. Displacement spectra for the first band of modes, measured at the bay centres, were compared with results due to acoustic excitation at grazing incidence. The vibration in the lower order modes is greater for the acoustic excitation but the converse is true for the higher order modes. Displacement cross correlation measurements show the presence of standing waves for distances up to three bay lengths but the wave system breaks down over larger distances. A comparison of random techniques used in structural damping measurements shows the autocorrelation decay method to be the most reliable. Using specially constructed gating apparatus, pressure measurements in the laminar-turbulent transition region show that the turbulent spots are autonomous regions of turbulent boundary layer, with similar pressure spectra. In addition there are low frequency pressure fluctuations due to the disturbances produced by the pressure steps on the mean flow. The background noise levels in the wind tunnel were measured.
