Mean Flow Effects on the Low-Wavenumber Pressure Spectrum on a Flexible SurfaceSource: Journal of Fluids Engineering:;1986:;volume( 108 ):;issue: 001::page 104Author:A. P. Dowling

Abstract: The Lighthill theory is extended so that it may be used to determine the flow noise induced by a turbulent boundary layer over a plane homogeneous flexible surface. The influence of the surface properties and the mean flow on the sound generation is brought out explicitly through the use of a Green function. The form of the low-wavenumber wall-pressure spectrum on a rigid surface with an arbitrary mean flow profile is determined. The effect of a coating layer is investigated.
