Residence time of water film and slug flow features in fuel cell gas channels and their effect on instantaneous area coverage ratio

Water in the gas channels of a Proton Exchange Membrane Fuel Cell is modeled as slugs and film, and removal mechanisms for these flow patterns are numerically investigated. The removal of excess liquid water is simulated using computational fluid dynamics (CFD) through the volume of fluid (VOF) mode...
