At low gas velocities, it is possible for counter current two-phase flow to occur with the gas going upwards, and the liquid falling as a film on the channel wall. At the other extreme, when the gas velocity is high, the liquid flows upwards in the film, and we have Annular Flow. As the gas flow is increased, the system passes from one of falling film flow through the
