Deformation of cavitation bubbles arranged in a line during their strong expansion-compression

The features of influence of hydrodynamic interaction between weakly nonspherical bubbles on their deformation during the process of their strong joint expansion-compression are investigated. The centers of the bubbles are located in a straight line. It is found that the bubble deformation during the expansion-compression is slightly dependent on their initial nonsphericity. The central bubbles undergo smaller deformations as compared with those on the periphery. If the number of the bubbles is large enough, then their central part is deformed practically in the same way. At the final high-speed stage of compression interaction between the bubbles is inessential.
