| Abstract: | The hydraulic performance problems of the low-specific-speed centrifugal pump designed by traditional, methods are discussed. The hydraulic design methods for low-specific-speed centrifugal pump are reviewed and compared, such as the large flow rate design, no-overload methods, area ratio principle and splitter-blade method. The experimental results and design theory for low-specific-speed centrifugal pump with splitter blades are detailed. The history advance about pump design theory, velocity field measurement techniques and mathematical simulation are briefly reviewed, and the trends for further research are also discussed. |
| Keywords: | low-specific-speed impeller with splitters hydraulic design velocity field measurement mathematical simulation |
