“…The parallel plate geometry is commonly employed in industrial electrochemical processes (14). Many novel cell designs aimed at enhancing mass transfer rates have been invented in recent years, e.g., using magnetic fields (15), wiped plates (16), very high flow rates (17), ultrasonic waves (18), and controlled abrasion of the plate (19). One method of improving the mass transport conditions in a parallel plate (rectangular duct) electrolysis cell is to orient the cell so that the less dense electrolyte solution is produced below electrolyte of higher density, e.g., by employing an upward facing cathode in electrodeposition.…”

When a metal is electrodeposited in laminar flow onto a planar cathode facing upward in a channel, mass transfer rates are enhanced downstream beginning at some distance from the leading edge, because of the contribution of free convection to the fluid motion. The position and extent of this secondary flow has been clearly demonstrated by double beam interferometry, employed for the measurement of concentration profiles in the cathodic boundary layer. A narrow range of critical Rayleigh numbers, 1270±200 , has been associated with the onset of natural convection. This result provides a convenient basis for the prediction of the transition from forced convection control to combined forced and natural convection control of the mass transfer process.
