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.

Although the study of wall pressure fluctuations (WPFs)has a long and venerable history, relatively little is known about the nature of the source terms responsible for the wall pressure. This study takes advantage of the three-dimensional velocity fields available from turbulence simulations to try to answer some long-standing questions about the nature of WPFs. Which parts of the boundary layer generate the various wave number regions of the wall pressure? What are the dominant source terms? What are the relative magnitudes of the mean-shear (MS) and turbulence-turbulence (TT)wall pressures? What physical processes in the boundary layer generate the wall pressure?
