Abstract
Through an experimental examination on the complete dissolution of nitrogen-gas bubbles in water, the mechanism of mass transport is shown to be consistent with a model comprised of two processes: (1) the primary and rate-limiting process is modelled by the diffusion of gas through an unstirred liquid-boundary layer whose thickness varies with bubble radius; and (2) a second-order limitation is due to the nonequilibrium transport of gas across the phase boundary as predicted by a statistical rate theory expression. The theoretical model is then applied to predict the evolution of a bubble towards a state of stable equilibrium.
