QUANTIFYING SURFACE NOISE SOURCES PRODUCED BY BOUNDARY LAYERS AND SURFACE MOUNTED OBSTACLES
Abstract
A comprehensive 4-year research program is proposed focused on measurements to document and understand the noise-producing low-wavenumber pressure fluctuation field of high Reynolds number turbulent boundary layers and of surface-mounted obstacle wakes. Our goal is to providethe physical information and insight needed for the development of improved wavenumber frequency models for the fluctuating wall pressure in boundary layers, as well as models that can account for pressure gradients, the far wakes of a broad class of spatially compact obstacles placed on the flow surface, and ultimately the effects of clusters of obstacles or roughness. This study willbe collaborative with parallel theoretical work being proposed by Stewart Glegg from Florida Atlantic University, and computational studies being proposed by Meng Wang from the University of Notre Dame. We also anticipate collaboration with NSWCCD, through Jason Anderson.
