Investigation on Numerical Simulation of Chloride

Nov 17, 2021 · The chloride content in the boundary conditions of the numerical simulation was based on the experiments, but it is not exactly the same as experiment results. It should be noted that the boundary chloride content (0.2%) at 293.15 K (20°C) was artificially set, which means that the influence of boundary chloride content on chloride
