    WALL-JET ELECTRODES - THE IMPORTANCE OF RADIAL DIFFUSION by Compton, R, Fisher, A, Latham, M, Wellington, R, Brett, C, Brett, A

    Published 1993
    “…Existing models for mass transport to wall jet electrodes (WJE) are critically re-evaluated in the light of some new calculations and experiments which relate to steady state and transient currents observed at wall jet ring disc electrodes both in the presence and absence of homogeneous chemical kinetic complications. Specifically, it is concluded that in many cases quantitative descriptions are only realisable if transport to the electrode is described as having a significant contribution from radial diffusion in addition to the radial convection and normal diffusion that are usually only considered. …”
