Propagation of Small Disturbance Waves in a Fluid Flow across the Junctions between Rigid and Compliant Panels

Abstract

The problem of wave propagation in a fluid flow across the junction between the rigid and the compliantpanelsin a channelhas beenstudied.In vorticalTollmien-Schlichting-type waves, thejump conditions are obtainedby the half-Fouriertransforms definedon both the sides of thejunction along withthe adjointmethod. The methoddevelopedis fairlygenericand is applicableto similarproblems. A comparison of the results obtained in the present study with those obtained from direct numerical simulations' shows good agreement.
