Overall mass transfer to the rotating inner electrode of a concentric cylindrical reactor with axial flow

Overall mass transfer coefficients between a liquid flowing axially in an annulus and the surface of the rotating inner cylinder have been determined electrochemically. The experiments concern mainly the laminar vortex regime and the results show the combined effect of rotation and axial flow. The value 300 of the axial Reynolds number separates two domains; for each domain the results are satisfactorily correlated using dimensionless numbers.
