Electrodes of Impressed Current Cathodic Protection systems used to inhibit corrosion of ship hulls, are areas where Chlorine is produced. It has been observed that certain concentrations of such oxidants can lead to the reduction or even reversal of the accumulation of biological fouling on ship hulls. In this paper a multiphysics modeling and simulation framework of such a process is developed and applied for a typical electrolytic cell. The framework is based on a coupled chemical reaction – electric currents – convection – diffusion and electromigration model aiming at providing transient solutions of the Chlorine species concentration in the volume of the cell. Finite element analysis results are presented for the relevant partial differential equations of the spatio-temporal evolution of the involved species and current density for the geometry of the electrolytic cell.
