Abstract EN
Centrifugal pumps can be operated in reverse as small hydropower recovery turbines and are cheaper than bespoke turbines due to their ease of manufacture.
Splitter blades technique is one of the techniques used in flow field optimization and performance enhancement of rotating machinery.
To understand the effects of splitter blades to the steady and unsteady influence of PAT, numerical research was performed.
3D Navier-Stokes solver CFX was used in the performance prediction and analysis of PAT’s performance.
Results show that splitter blades have a positive impact on PAT’s performance.
With the increase of splitter blades, its required pressure head is dropped and its efficiency is increased.
Unsteady pressure field analysis and comparison show that the unsteady pressure field within PAT is improved when splitter blades are added to impeller flow passage.
To verify the accuracy of numerical prediction methods, an open PAT test rig was built at Jiangsu University.
The PAT was manufactured and tested.
Comparison between experimental and numerical results shows that the discrepancy between numerical and experimental results is acceptable.
CFD can be used in the performance prediction and optimization of PAT.
