Abstract

We develop an analytical solution for the fully coupled response of a cavity-backed thin plate mounted in an infinite rectangular duct assuming linear dynamics at a fixed temporal frequency. The plate is subjected to harmonic planar acoustic waves at grazing incidence in the presence of uniform mean flow in the duct. The coupled response of the plate in presence of flow in duct is presented. It is found that the presence of flow modifies the peak amplitude of the plate response with negligible shift in frequencies at which the response peaks.
