Abstract

The growth in the amplitude of the small nonsphericity of cavitation bubbles in acetone and water under strong compression is considered. A hydrodynamic model is used in which the compressibility of the liquid, the nonstationary thermal conduction of the vapor and the liquid, and nonequilibrium evaporation–condensation processes, as well as imperfection of the vapor, are considered. It has been shown that the increase in the amplitude of the small nonsphericity of cavitation bubbles in the form of separate spherical harmonics during compression in water is substantially (more than 10 times) higher than during compression in acetone. This indicates that acetone is much more advantageous over water to implement a process of the nearer-to-spherical extreme compression of the medium in the cavitation bubbles.
