Simulating Microbubble Flows Using COMSOL Multiphysics
Acute respiratory distress syndrome (ARDS) is a severe lung disease caused by a variety of direct and indirect insults. The main treatment for ARDS is mechanical ventilation. The ventilation of fluid filled lungs involves the propagation of microbubbles over a layer of epithelial cells.
We utilized COMSOL® with MATLAB® to develop a time dependent computational model of semi-infinite air bubble progression in a liquid filled channel. As a result, we are able to obtain very accurate and stable solutions at very small capillary numbers compared to other methods during the simulation of the air liquid bubble interface movement.
