Numerically Efficient Model for the Nucleation, Growth, and Coalescence of Bubbles in Magma
Journal of Geophysical Research: Solid Earth, Volume 130, Issue 11, November 2025.Abstract We present a numerical model to describe the nucleation, growth, and coalescence of bubbles in a decompressed magma. The new model enables us to calculate the bubble size distribution (BSD) at a low computational cost by taking the bubble mass as a variable.
