Radiation Impedance Calculations with the XWAVE Computer Program,

Abstract

The report describes a method for calculating the acoustic radiation impedance of a vibrating structure submerged in an infinite fluid, via the solution of an integral equation relating normal surface velocity and pressure. The numerical solution of the integral equation is accomplished through use of the acoustics radiation program XWAVE. The advantage of this approach is in its applicability to structures with arbitrary surface geometry. The method is demonstrated by a calculation of the self-acoustic radiation impedance of a uniformly vibrating ring set in a rigid prolate spheroidal baffle. Computed results are compared with existing analytic solutions. (Author)
