Radiation of sound from a monopole source near a free-flooded cylindrical shell

Open publisher page 0 citations

Abstract

Radiation of sound from an acoustic source changes if there is a structure nearby. Radiated and scattered acoustic pressure fields are obtained when a free-flooded cylindrical shell of finite length is subjected to acoustic waves from a monopole source. By solving integral equations formulated for an elastic thin shell with simply supported boundary conditions at both ends, far-field acoustic pressures are calculated. Cases of various source locations inside and outside a shell are discussed.
