DOME EFFECTIVENESS AND THE SCALING AND AREA DEPENDENCE OF BOUNDARY-LAYER PRESSURE SPECTRA VIEWED WITH REGARD TO CHARACTERISTIC WAVENUMBER RANGES

Abstract

In the design of sonar systems, achievement of optimum configurations, or positive control, for flow noise depends on adequately understanding its generation by pressure fluctuations associated with a turbulent boundary layer. The paper emphasizes certain facts and presumptions, mostly already recognized, and uses a corresponding characterization of the pressure field to point out relations depending mainly on the grosser and more immediately relevant properties, with application both to flush-mounted and dome-shielded elements and arrays.
