Numerical analysis of acoustic scattering from soundpermeable spheres under external influence

Abstract

A generalized mathematical model of acoustic scattering from a set of sound-permeable spheres, the centers of which are located on the same axis, under the influence of either a spherical wave from a monopole radiation source or a plane wave is presented. Numerical analysis is performed and diagrams of the pressure distribution inside and outside the spheres are presented for various values of the system parameters (the number of spheres, the radii of the spheres, the distance between the spheres, the angle of incidence of the external wave, the distance from the center of the first sphere to the monopole radiation source, the physical parameters of the external and internal media) and the type of external influence.
