Abstract

Pump casing has blockage effects on Impeller flow in a centrifugal pump such that the flow field around volute tongue has quite large change when the impeller rotates. A double suction pump is widely used in industrial world because it has lower NPSH required than a single suction pump. Thus, in this study, the interaction between impeller and volute casing has been investigated by using CFD for a double-suction centrifugal pump. Quasi-steady method and full pump model has been employed for the numerical calculation.
