Performance Analysis of Centrifugal Pump at Different Operating Mode
The aim of this research is to perform numerical simulation of centrifugal pump and PATs mode to analyse its cavitation characteristics and NPSHr at different operating conditions. It was found that maximum efficiency at design discharge for the PAT is about 2 % less than the efficiency in pump mode. It is observed that the efficiencies increase steadily on increasing the discharge from 8.88 kg/s to 14.8 kg/s. in both pump and turbine mode. Thereafter the rate of increase in efficiency becomes very less when increase in discharge to 17.76 kg/s. Maximum efficiency of 59.49 % being achieved at 14.8 kg/s.
