Abstract
The mechanism and kinetics of spontaneous volume variation of a gas-filled void in a Newtonian continuum are investigated. Kinetic equations are derived, describing the variation of the void radius in the case where the process rate is limited by diffusion of gas into the medium surrounding the void. The dissolution of air bubbles in water is studied experimentally. It is found that the kinetics of bubble dissolution is sensitive to the individual characteristics of the gaseous component in the mixture (partial pressure, solubility, and diffusivity in the matrix). The experimental results are discussed in juxtaposition with the analytical part.
