Prediction of erosive wear – A novel mathematical model

Abstract

Several authors in past idealized erodent particles by assuming of spherical shapes. In reality, particles predominantly have irregular and angular shapes. The present study evolved a novel mechanistic mathematical model for prediction of solid particle erosive wear assuming the angular particles of square pyramidal shapes. The proposed model predicts the absolute volume loss as a cumulative contribution of deformation damage and cutting removal. It includes the effect of velocity, impingement angle, mass, abrasiveness factor of striking particles and the properties of target material. It can be effectively used for prediction of erosive wear for jet type of fluid flow.
