dc.description.abstractA two-phase mathematical model is applied to numerical investigation of gas evolution in a vertical electrochemical cell. The model comprises transport equations derived from first principles for each phase. Void fraction distribution for both hydrogen and oxygen gases velocity of gas and liquid phases, concentration and current density distribution are calculated. It is found that gas fraction increases towards to the top of the cell. Gas phase confined regions at the vicinity of the electrodes. Gas release significantly affects the velocity profile in the system. The large density differences between two-phase generate flow which modify velocity profile. Gas release is enhanced at high current density however; gas layer accumulated on the electrode surface decreases the active reaction area which adversely affects the reaction rate. © 2003 Elsevier Inc.
