An open pump as turbine(PAT)test rig was built to examine the relations between pump and PAT performance characteristics
and its two models' internal flow field. The experiment on a single stage centrifugal pump was conducted to study its performance characteristics under normal and reverse operating conditions. The results show that the reverse operating centrifugal pump has high efficiency. The numerical simulation on the pump and the PAT was performed by adopting all domain and structural mesh technique
and the simulation results are in reasonable consistency with the experimental data. Additionally the analyses were performed on the pressure field and the velocity field inside the pump and the PAT.
