Pagination or Media Count:
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.
