Abstract
The interactions between two deformable bubbles are studied in order to determine the effects of deformation on bubble dynamics and to determine the limits in which the effects of deformation can be ignored. Deformation due to hydrodynamic interactions with other bubbles leads to alignment of horizontally offset bubbles and thus an enhanced rate of coalescence. Bubble alignment may produce spatial inhomogeneities in bubble concentrations in magmas, which implies temporal variations in the concentration and size of bubbles in erupting magmas and spatial variations in solidified lavas. An approximate quantitative model for the rate of coalescence of deformable bubbles is developed based on a series of experiments. The effects of deformation can be ignored if the largest bubbles have radii less than about 5 mm in silicate magmas.
