摘要
Abstract
The 3D modeling software Pro/E was used to model the centrifugal slurry pump.The RNG k-ε model was used for solving the N-S equations.The governing equations for slurry pump internal flow were discretized using the finite volume method, and the SIMPLE algorithm was applied for flow field calculation.Results of the numerical simulation were analyzed to explore the effects of the initial concentration of solid phase, the solid particle size and the impeller structure on the velocity and pressure fields at the impeller and in the volute chamber.The abrasive wear behaviors at flow components of the slurry pump were analyzed, and the erosion characteristics of solid particles were investigated.The acquire results were expected for providing reference for improving the anti-wear properties and the hydraulic design of the slurry pump.关键词
