Abstract:

A three“dimension turbulent flow through all the parts of a single-stage centrifugal pump(such as the in.let pipe,the impeller and the pump volute)is numerically simulated using the large.eddy simulation model of FLU.ENT software in a multiple reference frame.It is found that the flow rate.the flow speed and the Dressul'e in all passages of the impeller are remarkably different from each other,which means that the flow is 0bvi0uslv asvmmet.ric,and that the voriex and reverse flow mainly takes place at the pressure sides of impeller blades.The efficiencv of the calculated results is finally verified by the comparison between the predicted and the measured values
