  • Numerical and experimental investigation of a single stage centripetal pump
    Gantar, Tine ; Sekavčnik, Mihael ; Mori, Mitja
    In the present paper a numerical and experimental investigation of a single stage centripetal pump (SSCP) is presented. The SSCP was designed using CAD and CFD tools. The performance curves of the ... SSCP were measured in a test facility with water involved as the working media and compared with the calculated ones. The measured performance curves are characterised by the region of hysteresis since the throttle closing performance curves do not correspond completely to the throttle opening performance curves. The deliveryhead and efficiency are abruptly decreased when reducing the flow ratefrom the point of the maximum delivery head. Due to the evident analogy ofthe SSCP and the axial-flow compressors performance curves and similarities in the rotor design it can be anticipated that such an operating behaviour of the SSCP is caused by the rotating stall phenomenon. CFD simulations confirm that the stalling of the rotor passages causes the steep delivery head drop when decreasing the flow rate from the point of maximum head.
