Abstract: The paper deals with nucleation and dynamics of bubbles in water with dissolved contaminant gas. The nucleation model assumes binary solution of water and pure gas. Some attention is paid to the study of the effect of the dissolved gas on the onset of nucleation (cavitation). In addition, the presence of the gas component is reflected in the Rayleigh-Plesset equation, which describes the subsequent growth (and dynamics) of a bubble in a liquid. The derived equation for bubble radius assumes mass transfer across the bubble boundary, which is in the contrary to the previous and widely used assumptions of boundary impermeability and which appears to provide more realistic insights into bubble behavior. The effect of mass transfer across the bubble boundary is studied analytically and numerically. The natural frequency of the bubble is also shown for the studied problem.
