Features of the interaction of a bubble and a solid spherical particle in the presence of an acoustic field in the three-dimensional case are numerically studied using the boundary element method for potential flow. Multiparametric calculations are presented and dependences of the change in the volume of the bubble, dynamics of the mass center of the bubble and particle on the distance between the objects and their sizes are constructed. It is shown that during the bubble expansion, the particle repels from it, and during the bubble shrinkage it is attracted, the size of the particle determines its mobility. On average, over five periods of acoustic field oscillations, the distance between the objects decreases, which is due to the translational motion of the bubble in the compression phase. The features of the deformation of a bubble located near a solid spherical particle with small amplitudes of the acoustic field are studied.
