Description
Summary:Numerical method which can accurately predict pump's performance has been obtained in this paper. Flow in centrifugal pump equipped with a conical suction, a conical suction with swirl stop, and a center baffle suction has been simulated respectively. With comparison of the pump performance curves, it indicates that the three suctions almost have the same effect to the pump, and the center baffle suction has worse performance. The flow structure at partial flow rate in the pumps is simulated in this paper too, and serious back flow is found in the flow passage of the impeller. Amounts of water flows back to the impeller inlet so that the uniformity of the inflow is disordered. Then the back flow occupies the whole flow passage and the flow is nearly cut off.
