Abstract

The sudden rupture of liquids behind strong tension waves, which is significantly affected by cavitation nuclei, is called heterogeneous shock cavitation. The process of cavitation is described by a microbubble model, taking into account the dynamics of the individual cavitation nuclei. The effect of different parameters, such as the amplitude and steepness of the tension wave and the properties of the liquid on the characteristics of heterogeneous shock cavitation, is numerically investigated. The number density of cavitation nuclei, but not their size, turns out to play a predominant role for heterogeneous shock cavitation within wide bounds.
