Anode Film Resistance Effect on Cathodic Corrosion Protection
Application ID: 21101
This model exemplifies how the rate of steel corrosion in an oil platform increases over time due to build-up of a resistive film on the sacrificial anodes, formed by reaction products.
The model also includes secondary current distribution electrode kinetics on the protected steel structure, defining simultaneous metal dissolution and oxygen reduction (mixed potential).
This model example illustrates applications of this type that would nominally be built using the following products:
however, additional products may be required to completely define and model it. Furthermore, this example may also be defined and modeled using components from the following product combinations:
- COMSOL Multiphysics® et
- soit le Module Battery Design, Module Corrosion, Module Electrochemistry, Module Electrodeposition, ou Module Fuel Cell & Electrolyzer
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Grille des Spécifications and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
