Abstract

The supercompression method, consisting in a nonperiodic change in the external pressure, is applied to a cluster of gas bubbles in an unbound viscous, slightly compressible fluid. The effect of dissipation of the kinetic energy associated with the viscosity of a liquid and acoustic radiation on the dynamics of a bubble cluster is considered. The oscillations of a single bubble and bubble in a monodisperse cluster are compared, as well as a comparison of bubble oscillations in mono- and polydisperse clusters.
