Invited: Simulation of the acoustic filed of a structure vibrating in a subsonic uniform flow using the fast BEM

In this paper, the acoustic radiation of a structure vibrating in an uniform subsonic flow is investigated using the pre-corrected fast Fourier transform accelerated BEM (pFFT-BEM). The governing equation together with the boundary conditions are transformed into the classical Helmholtz wave equation and the corresponding boundary conditions. The pFFT-BEM is then applied to simulate the acoustic field. A vibrating spheroid in a subsonic uniform flow is simulated to validate the algorithm.
