Development and Nobel Application of Numerical Corrosion Simulation

Abstract

Numerical simulation is gathering many expectations in the field of corrosion engineering with the development of computer. In this review the two example topics are introduced.
The first topic is “Numerical method for time-dependent localized corrosion analysis with moving boundaries”. The numerical method for time-dependent localized corrosion analysis is presented. Electromigration, mass diffusion, chemical reactions, and moving boundaries are considered in the numerical simulation of localized corrosion of engineering alloys in an underwater environment. The method combines the finite volume method （FVM）and the voxel method.
In the second topic, the forecasting system of the current from sacrificial anodes using data assimilation was introduced.
Some numerical verification example analysis are shown to demonstrate the effectiveness of the methods.
