Main results: Mathematical model of the bubble cluster has been elaborated and on the basis of this model the numerical investigations have been made. The results of these investigations are the following. Dynamics of bubbles in cluster is much differ from dynamics of a single bubble. In polydisperse cluster (with bubbles of different sizes) the synchronization phenomenon of collapse phases takes place. At some parameters the collapse intensification of the bubbles of one radius in the presence of the bubbles of other radius is observed. The investigation of the rectified diffusion in polydisperse cluster shows that the cluster has a tendency to become monodisperse.
