In the measurement of fluctuating concentration and velocity of turbulence in the concentration polarized system, electrolysis on the fully developed rotating disk electrode, as a cathode, is not able to determine accurately those values, as the width of the disk electrode is too larger compared to the scales of turbulence to provide an uniformly linear accessibility. In order to obtain the uniformly or linearly accessible surface and determine the correlation coefficient of turbulence, the typical RING ELECTRODE is considered. Different thin platinum wires are arranged with different distances in the direction of the streamlines on the disk and the other areas of the surface are artificially insulated. Under the necessary assumptions, herein, a theoretical analysis is consistent with the experimental data obtained by other investigators. The edge effect in the arrangement of the uncoated sections and at the edge of the disk is adjustable with the typical geometry for being compensated with turbulent properties but it must be unavoidably negligible for the theoretical analysis on the rotating disk. Gas evolution, non-uniform current density and overpotentials are also controllable, more or less, with the typical structure of the system. Further investigations of the flow near corner, corrosion, and contamination of the ring electrode surface should be studied.
