Electrodeposition on a circular cylinder under forced convection was simulated for Reynolds numbers 10 and 200 by numerical solutions of the incompressible Navier-Stokes and mass transport equations. Current density distribution and concentration fields were computed with changing mass transfer and flux rates. Comparisons with earlier numerical and theoretical results are presented for Reynolds number 10. It is shown that the unsteady wake that appears for Reynolds numbers greater than 50 affects the mass transfer from the surface of the cylinder only in an average sense. This result is compared with a heat transfer case, where unsteadiness is much more manifest.
