✦ Synopsis

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 laminm 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. NOMENCLATURE coefficient in (1) exponents in (1) diffusion coefficient intercylinder gap width length of the cathode outside radius of the inne.r cylinder inside radius of the outer cylinder axial Reynolds number = u .Ze/v Reynolds number for rotation = 2 R: . w/v
