Flow Induced Structural Noise on a Sonar Dome of a ShipThe turbulent boundary layer pressure field on the exterior of the sonar dome is the major contributor of the sonar self-noise above a certain speed of the vessel. In particular, interior noise levels are influenced by hydrodynamic ...
The turbulent boundary layer pressure field on the exterior of the sonar dome is the major contributor of the sonar self-noise above a certain speed of the vessel. In particular, interior noise levels are influenced by hydrodynamic coincidence, which occurs when the convection speed in the ...

Selection of a Suitable Wall Pressure Spectrum Model for Estimating Flow-Induced Noise in Sonar Applicationsdoi:10.3233/SAV-1995-2506V. Bhujanga RaoHindawiShock and Vibration
In this paper we present an investigation of flow noise in sonar applications. Based on a careful identification of the dominant coupling effects, the acoustic noise at the sensor position resulting from the turbulent wall pressure fluctuations is modelled with a system of hydrodynamic, bending and ...
