Mixing is characterized in liquids moving between bubbles when the bubbles are moving down a microfluidic channel. The shape is assumed based on fluid mechanical arguments and experimental observations, and the mixing is characterized for a variety of situations in two and three-dimensions. In COMSOL Multiphysics, an integration coupling variable was used by solving the problem in two dimensions and using it for the inlet velocity in the three dimensional problem.
