✦ Synopsis

Ah&act-The

influence of surface tension upon the dissolution and growth of a stationary, isolated gas bubble in a fluid is examined. It is demonstrated that for small gas undersaturation of the liquid, surface tension corrections for bubble dissolution are significant for nearly the entire period of bubble dissolution. Also, it is shown that for slight supersaturation of the liquid, when bubble growth occurs, sutface tension corrections are non-negligible too. Furthermore. comparisons are made with the quasi-stationary results which seem to indicate that surface tension corrections are of greater significance than convective corrections for small undersaturations. In the case of large undersaturations surface tension corrections are only of importance when the radius of the bubble is small.

A simple equation is derived for the time dependence of the bubble radius for the diffusion-induced slow growth or dissolution of a spherical gas bubble in a viscoelastic fluid of infinite extent. The constitutive equation for a first-order fluid and a surface-volume perturbation scheme are used to
