Abstract: Analytical solutions of the problem of collapsing of a spherical shell or cavity in an ideal compressible liquid having a constant density during its motion are constructed. The influence of the gas located in the cavity on the motion of the cavity boundary is studied. A quantitative characteristic of energy cumulation is proposed. An expression for energy cumulation in the case of shell or cavity collapsing is derived. The energy cumulation obtained in this study is compared with Zababakhin's results.

Keywords: cumulation, incompressibility, pressure, energy, velocity, energy release.
