Mass transfer of a rotating disk in transition flow
An experimental study of mass transfer to a rotating disk electrode was employed to determine an empirical correlation for the mass transfer rate in the Reynolds number regime lying between simple laminar and turbulent flows. This domain, apparently characterized by a regular vortex pattern, was found to extend from a Reynolds number of 2.0 x 10/sup 5/ to approximately 3.0 x 10/sup 5/. The resultant correlation for the average transfer rate, in terms of dimensionless Nusselt, Reynolds, and Schmidt numbers, is Nu = 0.89 x 10/sup 5/ Re/sub 0/ /sup -//sup /sup 1///sub 2//Sc/sup /sup 1///sub 3// + 9.7 x 10/sup -15/ Re/sub 0//sup 3/Sc/sup/sup 1///sub 3//. The result is strictly applicable to the case of a uniform surface concentration; that is, to the limiting-current condition. (6 figures)
