Mathematical models for erosion and corrosion in power plants. A review of applicable modelling optimization techniques

Abstract

Surface damage in power plants causes economic loss and waste of operational time in modifications or repair. The wear is caused mainly by solid particles and water droplets. Erosion and corrosion of protective coatings constitute a number of significant engineering difficulties. “Trial and error” type methodology to improve the materials design is rather expensive, inaccurate and time consuming. Mathematical modelling through optimization methods overcome these engineering complications/difficulties, and reduce the experimental/tribotesting period. In this paper we provide a brief review of the current classified erosion and/or corrosion models and, additionally, detailed modern optimization methods for precise modelling of given applications. A concise computational optimization example for an erosion model is presented with brief software details/approximations.
