Slurry systems are used for processing and transportation of mined ore, mineral or metal concentrates, tailings, solid wastes, etc. in the oil and gas, mining and wastewater industries. The handling, processing and transporting of these slurries can result in significant equipment wear. Depending on the solid concentrations and equipment geometry, there are different kinds of wear that can occur, such as impact or erosion and abrasion. Understanding the types of wear or damage mechanisms will aid in selecting and/or developing appropriate models to predict wear rate. In this work, we discuss abrasive wear in the context of slurry flow conditions, available models and their shortcomings, and application of computational fluid dynamics (CFD) to predict abrasive wear. In addition, some suggestions for modeling strategies have been presented and discussed.
