Mass transfer in the rotating electrochemical cell with vertical cylindrical electrodes: The effect of rotational rate and cell geometry on the limiting current density

摘要

The mass transfer in the rotating electrochemical cell with vertical cylindrical electrodes containing a binary electrolyte is theoretically studied. The Navier-Stokes equations in the rotating system of coordinates, the equations of ionic transfer of electrolyte components, which is caused by diffusion, convection, and migration, and the condition of electroneutrality are used as the mathematic model of the process. The effects of centrifugal force and Coriolis force are studied by using the numerical simulation; the effect of geometry of electrochemical cell on the limiting mass transfer rate is determined.
