The potential for reducing mass transfer limitation at vertical electrodes through the application of vibrations was investigated using the limiting current technique. A wide range of experimental conditions was used (frequencies of 0-25 Hz, amplitudes of 0-20 mm, and electrode heights of 3-130 mm) and both the instantaneous and the average mass transfer rates were measured. Up to 23-fold increase in the average rate of mass transfer was achieved by vibrating the flat vertical plates parallel to their surfaces. The results obtained were well correlated using a quasi-steady state approach for mass transfer across a boundary layer over a flat plate where the average vibrational velocity over a cycle was used as a characteristic velocity.
