Description

<p>This study aims at the representation of carbon-aluminium galvanic corrosion under a saltwater film environment. In the numerical simulation, multiphysics problems including electric field, electrophoresis, mass diffusion, chemical reactions and moving boundaries are taken into account. In the mass transport analysis, the simulator is speeded up by using an implicit method. In the chemical reaction analysis, distribution of pH and precipitation is accurately represented by considering 4 chemical reactions of aluminium ions. Additionally, the simulator is validated through galvanic corrosion experiments.</p>
