Combined heat and mass transfer during bubble absorption in binary solutions.

Bubble injection is an effective method for vapour absorption. This analytical study describes bubble behaviour from inception to collapse as it translates inside a sub-cooled liquid binary solution. A finite difference method is employed to solve the governing equations and their associated boundary conditions. Special consideration is given to the complex interface mass and heat transport process. Sub-cooled liquid temperature and concentration fields surrounding a collapsing bubble are described. Bubble heat and mass transport variables are presented. Bubble diameter and mass are also described over the bubble life span.
