Notes:
Simulation of the dissolution of an active corrosion pit in the presence of fluid flow was carried out with the use of finite element techniques. The model included multiple species in solution, reaction equilibria and transport by diffusion, convection and migration. The mathematical model was used to examine the effect of fluid flow on the pitting of nickel in neutral chloride solution. The pit dissolution rate was found to decrease with increasing flow owing to potential field effects. The capabilities demonstrated in this paper represent a significant advancement in the modelling of pitting corrosion phenomena.
