Lattice Boltzmann simulation of solution chemistry for crevice corrosion Original Research Article

We apply the two-dimensional lattice Boltzmann method (2D LBM) to the simulation of solution chemistry for crevice corrosion. The 2D distributions of pH and electrical potential are obtained by the numerical simulation. The critical value of pH which brings about the rapid crevice corrosion and the incubation period until the solution reaches this pH are estimated from the simulation results. It is found that the estimated pH and incubation period are in nearly agreement with experiment.
