Wet end components of centrifugal slurry pumps used in the hydraulic transport of solids are subject to substantial erosive wear. Accurate prediction of the casing wear rate and location for a particular duty is beneficial for correct pump selection and design, maintenance planning, and elimination of emergency shutdowns. CFD multi-phase simulation using the Eulerian-Eulerian approach is being used successfully to determine the velocity fields and solids concentration in the centrifugal pump allowing for accurate predictions of casing wear patterns resulting from sliding abrasive wear. Simulation results for various single domain and multi-domain multiphase simulations are discussed. Emphasis is placed on results from a 3 dimensional, multi-domain transient, multiphase simulation and comparison to field data.
