| Abstract: | Equations for a boundary layer, written in self-similar variables, are integrated numerically to obtain distributions of concentration of ions Cu2+, H+, and SO42–; a hydrodynamic velocity; partial currents of electrolyte components; and the limiting current of copper deposition and determine the Rayleigh number for the system under consideration. The results are compared with an approximate analytical solution obtained earlier. |
