The tangential shear due to the volume and time-averaged pulsation velocity caused by thermally controlled bubble growth and successive cyclic departure is found to be responsible for the natural switch from the regime of isolated bubble growth and departure into the regime of mutual interaction bubble growth and departure as the temperature difference between the bubble interface and sorrounding liquid increases. The proposed theoretical model, based only on first principles. agrees well with the experimental data for boiling water to which it was compared. The new model, which successfully predicts the isolated and mutual interaction bubble departure size, and the quantitative description of the natural transition between the two regimes are the essential new features of this work.
