ON THE GENERATION OF WALL PRESSURE FLUCTUATIONS FOR TURBULENT BOUNDARY LAYERS OVER ROUGH WALLS

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.
