ABSTRAKT

A mathematical model for the dynamics of a vapor bubble in chemically reacting solution has been formulated and numerically realized on a computer with due account of the kinetics of chemical reactions and phase transitions for the cases of a stationary bubble in the liquid volume and floating up under the effect of lifting forces. The model describes the bubble dynamics in the chemically inert liquids and solutions under limited transitions. The results of numerical investigation on growth and collapse of vapor bubbles in the volume of chemically reacting and inert liquids are presented. The comparison of the mathematical model with the available experimental data shows good agreement.
