Erosion modelling: a systematic review of available models and equations

Abstract

Abstract Across the years there was an increased attention drawn by erosion modelling, both as a general approach and also towards pipeline applications (with a concentration on pipe bends). Several authors have studied the phenomena and tried to explain the mechanisms and factors affecting the emergence and magnitude of erosion. Most of the proposed models and equations were developed for ductile materials, with a smaller part looking also at brittle materials. There are several differences observed, starting with the proposed wear mechanism and continuing with the parameters used in the equations as significant factors (for the erodent particles, target material and working conditions). The most important models and equations are analysed and presented in this article and a systematic visual representation is used to ease and simplify the understanding of the erosion modelling evolution across the years (erosion modelling in general conditions, empirical erosion modelling in pipes and bends, CFD erosion modelling in pipes and bends).
