Acoustic Structure Interaction with Damping Interface

Abstract

— This paper deals with the finite element method to compute the vibrations of a fluid -structure coupled system. The fluid structure system consists of an acoustic fluid and a plate structure. The Finite element analysis is done with and without the interphase damping and the results are compared. The damping material separates both the media, the fluid and the structure. The plate structure is described by a displacement field which contains an inviscid, compressible and barotropic fluid. The barotropic fluid is described by a pressure field. The gravity effects are neglected in the study. The aim of this study is to develop new noise reduction techniques in fluid structure interaction. The originality of the work lies in introducing a damping interphase in fluid structure interaction using ANSYS software and also intends to develop a simulated experiment of impedance tube.
