Abstracts:

In the present work the mechanism of growth of cavitation bubble in the metastable high-viscosity liquid (supersaturated magmatic melt) is investigated. Limitation of most frequently used in the literature model of bubble growth based on the quasi-steady diffusion is shown. An analytical solution describing the evolution of bubble growth under condition of dynamic equilibrium on its boundary is found. This assumption is applicable to a wide range of initial values of decompression. The comparison of calculation results with experimental data is made. The good agreement is achieved.
