Abstract: An experimental analysis of the flow structure and dynamics of the formation of a quasi-empty discontinuity upon shock excitation of a liquid layer showed that closure of the discontinuity at the final stage assumes a nearly one-dimensional cylindrical character. A new formulation of the dynamics of the cavitation zone behind the front of a converging rarefaction wave is investigated. Cavitation is initiated by shock-wave loading by a piston near the axis of the liquid layer bounded by the free surface. The paper presents the results from an analysis of how the sizes of microbubbles and concentration of the gas phase influence the dynamics of the cavitation zone and structure of the wave during focusing. The article was prepared based on materials in a report at the Third All-Russian Acoustics Conference (September 21–25, 2020, St. Petersburg).
