摘要

In this paper, a time-domain equivalent source method (ESM) for acoustic scattering prediction is suggested, based on acoustic velocity formulations. Incident and scattered acoustic predictions are realized by acoustic velocity formulation VIA of Ghorbaniasl. Formulation V1A is based on the FW-H equation and allows direct evaluation of the boundary condition, without requiring acoustic pressure gradient computation. The scattering approach is implemented and validated by the analytical case of scattering of a pulsating monopole source by a rigid sphere. The developed methodology is efficient for scattering problems where broadband noise sources are considered. (C) 2019 Elsevier Ltd. All rights reserved.
