Analytical Evaluation of a Flush-Mounted Hydrophone Array Response to a Modified Corcos Turbulent Wall Pressure Spectrum

Abstract

This report describes the analytical evaluation of the performance of an array of rectangular hydrophones mounted on a rigid surface in the reduction of flow noise, using a modified Corcos. This report also compares the results obtained from the modified Corcos model with those calculated for the original Corcos model. Mathematical details that follow the procedure described in an earlier work are given for the evaluation of the frequency spectral density. This work provides a tool for a quick estimate on the response of an array of hydrophones to turbulent boundary layer pressure fluctuations.
