A Guide to Use of the XWAVE Program. Part II. Scattering of Sound Waves from Rigid Structural Surfaces,

Abstract

This report reviews a generalized formulation of the steady-state boundary value problem for scattering of infinite plane waves by an arbitrary closed rigid surface immersed in an infinite fluid. The normal velocity distribution generated over the closed surface by scattering of plane waves can also be interpreted as the boundary condition of an equivalent steady-state radiation problem. The numerical solution of rigid surface scattering problems is therefore obtainable by a simple extension of capabilities of the XWAVE program. The additional data required by XWAVE for rigid-surface scattering applications and several sample calculations are presented. (Author)
