Abstract
Slurry erosion is a mechanically induced wear observed in various industries transiting the mixture of liquid and erodent particles, either naturally or affectedly. The equipment and pipelines need frequent monitoring and slurry erosion prediction to check the severity of erosion for implementing preventive measures to minimise the damage of erosion wear. Experimental investigation and online condition monitoring are very high priced and provide a fair idea about the extent of slurry erosion wear; nevertheless, precise prediction of slurry erosion wear requires in situ operating conditions. To minimise expenditure on slurry erosion testing or monitoring and accurate slurry erosion prediction, tribological modelling of slurry erosion wear by mathematical approach or computer-based simulations has proved to be an excellent approach by numerous researchers to foresee the slurry erosion wear and control its severity. Several authors in the past have aligned their efforts in this direction. This two-part review is an attempt to estimate the progress in the variety of tribological modelling (primarily mathematical models) of slurry erosion for its forecasting, monitoring and to suggest the apt approach for the modelling of slurry erosion wear, especially for hydroturbine components. This article covers the research studies pertaining to mathematical wear models for solid particle erosion recommending a commencing approach for slurry erosion wear modelling.
