Аннотация

The bubble growth process in a magmatic melt during decompression at a constant rate under various conditions is numerically studied. The effect of the formation of a narrow boundary layer with a high viscosity around the bubble, which significantly changes the dynamics of the bubble, is taken into account. It is shown that, at a low initial pressure in the medium, in the bubble high pressure is maintained throughout the calculation time. In the case of long decompression time, the final bubble radius is bigger than in the case with small decompression time. This effect can be associated with different dynamics of the medium viscosity in a narrow boundary layer around the bubble.
