NPSHr Optimization of Axial-Flow Pumps

Wen-Guang Li
Journal: Journal of Fluids Engineering
Publisher: ASME
Article Type: Technical Briefs
J. Fluids Eng. July 2008, 130(7): 074504.
https://doi.org/10.1115/1.2948368
Published Online: July 22, 2008
...Wen-Guang Li The two-step method for optimizing net positive suction head required (NPSHr) of axial-flow pumps is proposed in this paper. First, the NPSHr at the impeller tip is optimized with impeller diameter based on experimental data of 2D cascades in available wind tunnels...
