LOW-WAVENUMBER CONTENT OF THE SPECTRUM OF THE WALL PRESSURE UNDER A TURBULENT BOUNDARY LAYER.

Abstract

The report deals with the low-wavenumber content of the wall-pressure spectrum under a turbulent boundary layer. A discussion is given of the importance of the low-wavenumber content for evaluating transducer attenuation. Comments are made on the lack of reliable experimental data regarding the low-wavenumber content. Calculations are presented to substantiate the above comments. Direct experimental measurements of the low-wavenumber content are reported. (Author)
