Реферат:
The effect of barodiffusion on the dynamics of gas bubble growth in a highly viscous, gas-saturated magmatic
melt undergoing rapid decompression is studied. A mathematical model of the process, which represents a joint dynamic and diffusion problem, is proposed. It is shown that as the bubble grows, a diffusive boundary layer is formed
around it, leading to the appearance of a large viscosity gradient in the melt and, as a consequence, to a large pressure
gradient. A semi-analytical solution of the problem based on the existence of a quasi-stationary state for the bubble
growth process is found. It is shown that the effect of barodiffusion is significant at the initial and transient stages
of the process. Its influence decreases with time and disappears completely at the stage of diffusion.
