Newman's similarity model of convective diffusion of ions through multi-ionic concentration boundary layer in the presence of electric field is generalized for non-linear velocity profiles in the diffusion layer, and put into a form that can be integrated by the Runge-Kutta method. The results of a numerical solution are compared with voltammetric data from the literature.
