CFD numerical simulation of sand-contained cavitation characteristics of axial-flow pump

To study the effect of sediment on cavitation in axial-flow pump, method CFD is employed to experiment internal flow field pump case clean water and sandy separately. The calculation done with different particle sizes concentrations. results show that as concentration increases, vortex range area blade will further increase, pattern impeller becomes more disordered. mechanism action size similar concentration. However, quite from value are significantly larger than water. By contrast, has little range. It proves does not have a great influence distribution, but main factor affecting performance pump. Moreover, disrupt promote development reduce
