The use of rotating zinc cylinders in a kinetic study of the diffusion- controlled displacement reaction between zinc metal and copper(II) ions is reported. It is found that the results are a good fit to the empirical equations which have been previously established for mass transport to a rotating cylinder. Some limitations to the technique are noted, including an effect which becomes more pronounced as the cylinder length is reduced.

The heat or mass transport to a rotating cylinder is obtained by solving the conservation equations for large Prandtl or Schmidt numbers. A modified mixing length, which includes the effect of centrifugal forces in terms of the Richardson number, is used. Explicit relations are presented for the heat or mass transport and a comparison is made with the experimental data over a range of Prandtl and Schmidt numbers from 190 to 11,000.
