Abstract

A numerically study has been performed to predict the dynamics of flow and mass transfer in the chemical solution of reactor. The solution exists between electrochemical cells. The mass and momentum conservation equations are used to describe the fluid motion. The code describes the effects of convection, diffusion, migration, chemical reaction and electrode reaction on the concentration, potential and current density distribution in an electrochemical reactor. The code has been tested through different cases including the prediction of flow in a binary electrolyte solution in natural convection and multi-ion electrochemical reactor where concentration, potential, current density distribution and concentration boundary layer can be compared with available experimental data and published numerical results.
