Parabolic flow velocity distribution in electrolysis with flow-through porous electrodes

Abstract

A mathematical model is derived for flow-through porous electrodes that accounts for the parabolic flow velocity distribution of solution in the electrodes. The model allows a better understanding of physical phenomena accompanying the operation of flow-through electroanalytical detectors. The model predicts a consistent variation with the length of the electrode of an experimental parameter, α, that had earlier been found experimentally but that remained unexplained.
