Notes:
Using the Karman-Pohlhausen integral method, an analysis has been made for turbulent flow on a rotating hemispherical electrode mounted on an inert support rod of equal radius. The resulting friction coefficient is then substituted into the Chilton-Colburn relation to give a rate equation for mass transfer at high Schmidt numbers. Experiments with a diffusion-controlled electrolytic system over a range of Sc from 910 to 6,300 confirm the validity of the theory for Re 〉 40,000. A comparison with the results of previous heat and mass transfer measurements reveals that the turbulent flow on the present geometry is different from that on a rotating sphere and on a hemispherical electrode mounted on a support rod of larger radius.
