The scattering of a fluid-structure coupled wave at a flanged junction between two flexible
waveguides is investigated. The flange is assumed to be rigid on one side and soft on the …

The present work highlights the scattering of fluid–structure coupled waves through a wave-
bearing cavity in rigid waveguide. The cavity is filled with compressible fluid and comprises …

Present communication addresses the scattering of the dominant acoustic wave mode
propagating from a semi-rigid waveguide. The underlying waveguide is tuned because of …

This article investigates the scattering characteristics of a flexible trifurcated lined duct
containing multiple-step discontinuities in a general context. A semi-infinite duct is …

The present study examines the fluid-coupled wave response of a stepped elastic
membrane discontinuity connecting a flexible shell to the annular rigid shell. The acoustic …

In this article, the attenuation of fluid–structure coupled modes of non-planar waveguide
