Abstract

Seawater conductivity is an important factor that affects the corrosion electric field of ship.Athree-dimensional boundary element method (3D-BEM) combined with nonlinear polarization curve was employed to investigate the influence of seawater conductivity on the corrosion electrostatic field. Numerical simulation results show that the electric field distribution is only slightly influenced by the conductivity.However, the intensity decreases with the increases of conductivity. The simulation results of the BEM model were compared with the results of the equivalent electric dipole model, and the results obtained by the two methods had high similarity, which demonstrated that the BEM model was effective. The former is a more convenient and concise modeling method that can better reflect the distribution characteristics of ship's corrosion electric field than the electric dipole model.
