Influence of Blade Thickness on Solid–Liquid Two-Phase Flow and Impeller Wear in a Ceramic Centrifugal Slurry Pump

The impeller blades of ceramic slurry pumps are usually very thick for the purpose prolonging service life. In this paper, numerical simulations and wear test were conducted to investigate influence blade thickness on solid–liquid two-phase flow in a centrifugal pump. was CFD validation. results show that incident angles solid particles increase with increasing thickness, which larger wrap particle trajectories. trajectories offset region collisions between pressure side take place towards exit lead more impacts suction side. good accordance pattern tested impellers, demonstrates method adopted paper is predictable abrasion experimental an alleviates leading edges blades; however, it also aggravates decreases pump performance.
