Sound Wave Scattering From a Rigid Sphere

Abstract

The Helmholtz integral equation may be formed by combining the scalar wave equation with Euler's equation for motion within a fluid. The solution of this integral equation yields the radiated pressure from a submerged, vibrating body and may be used to characterize the scattering of incident sound waves from bodies. In this report the scattering from underwater rigid spheres is investigated and results are presented for ka < or minus 8.0....
