Experiments have been performed on the roughness noise produced by a two-dimensional turbulent wall jet boundary layer flowing over short fetches of sandpaper roughness. A range of rough surface sizes were studied from hydrodynamically smooth through

This paper introduces a new method for measuring the spectral character of wall pressure fluctuations under turbulent boundary layers by measuring the sound that they radiate in the presence of hydrodynamically smooth sinusoidal ridges in the surface

Extensive measurements have been made of the roughness noise and wall pressure fluctuations produced by a wall jet boundary layer. Short sandpaper roughness fetches, with grit sizes from 220 to 20 were immersed in a 15 mm thick boundary layer and stu

An experimental study has been conducted to determine the low frequency behavior of an unstaggered flat plate cascade. The cascade was excited by a discrete upwash gust with most of its energy below a reduced frequency of 2. The results of this test

*† A computerized gust generator has been developed and tested for the Virginia Tech Stability Wind Tunnel. The generator consists of 10 airfoil section vanes spanning from the top to the bottom of the tunnel contraction. Computer controlled steppe

This paper considers two alternative mechanisms for sound generation by boundary layers over rough walls. The first mechanism is based on the concept, introduced by Howe, that the hydrodynamic pressure fluctuations in the boundary layer are scattered
