Prediction of Abrasive and Impact Wear Due to Multi-Shaped Particles in a Centrifugal Pump via CFD-DEM Coupling Method

Cheng Tang et al.

Summary: The study investigates the wear characteristics of a centrifugal pump using the CFD-DEM coupling method, showing that as particle sphericity increases, particles tend to cluster in specific areas within the volute, leading to principal wear erosion. Impact and abrasive wear within the impeller primarily occur on the blade leading edge, with the pump's overall wear rates changing differently with particle sphericity.
