The purpose of the work is to determine the optimal ways of solving "multiple scattering" problems for a system of spherical bodies in a cylindrical cavity with a liquid, to study the hydrodynamic characteristics of a system consisting of volumes filled with an ideal compressible liquid with droplets of other liquids immersed in them under the action of an acoustic wave , extending along the line that connects the centers of the drops, calculation of the acoustic pressure field in the system, determination of the acoustic hydrodynamic force acting on the drop, and calculation of the acoustic radiation forces in the system by averaging over time the obtained hydrodynamic force; study of the effect on acoustic radiation forces of the frequency of the primary wave, geometric and physical properties of the system components. Research methods - analytical methods of mechanics. The optimal way of solving the problem of multiple reflection is determined; the formulation of the problem of determining the forces of interaction in the system of two liquid drops in an acoustic field is formulated. The formula for the acoustic radiation force acting on the droplets was obtained. An analysis of the nature of the interaction in the system of two drops in the liquid, depending on the frequency of the primary wave, geometric and physical properties of the components of the system, was carried out.
