| 摘 要： | A numerical method of solving acoustic wave scattering pnblemin fluids is described.Radiation boundary condition(RBC)obtained byfactorization method of Helmholtz equation is applied to transforming theexterior boundary value problem in unbounded region into one in a finiteregion.Combined with RBC and scatterer surface boundary condition,Helmholtz equation is solved numerically by the finite difference method.Computational results for sphere and prolate spheroidal scatterers are inexcellent agreement with eigenfunction solutions and much better than theresults of OSRC method.
