Compression of cavitation bubble in viscous liquid

Abstract

This work is devoted to studying the compression of cavitation bubbles by viscous liquid and the rate of steam compression in it within a wide range of Reynolds numbers. The influence of heat conductivity in bubble, the compressibility of liquid and evaporation/condensation on the surface of the bubble have been studied. It has been shown that the maximal pressure inside of the bubble increases sharply in a small neighborhood of some critical value with growth in the Reynolds number. This critical value is close to the one established by Zababakhin, which separates regimes of the bubble collapse in incompressible liquid for finite and infinite times.
