The wear process known as erosion occurs when discrete particles (e.g. solid particles or water droplets) strike a surface. The process causes surface damage, leading to material loss and mechanical degradation, potentially causing serious problems and economic loss. Material degradation is often unavoidable but the ability to model the erosion process allows engineers to improve component/system design through better material selection and the use of erosion reducing measures.

In this paper, the current methods available for modelling erosion will be reviewed. The simpler models are empirical models that use mass (or volume) loss equations to predict the erosion rate. Mechanistic models can account for fluid and particle properties and flow rates. The more complicated models include Monte Carlo based solid particle erosion, computational fluid dynamics based models and finite element based models.
