Lattice Boltzmann simulation of electrochemical systems Original Research Article

We propose a lattice Boltzmann model for studying electrochemical processes. A new lattice Boltzmann equation is introduced to simulate ion transports, including migration in an electric field, diffusion in a concentration gradient, and convection with fluid flow. The electrode reaction is incorporated via special boundary conditions for electric potential and ion flux. Benchmark studies on a variety of electrochemical problems, including the convective diffusion, the primary and secondary current distributions, and a general case, yield satisfactory results.
