Optimization Design of Super Low-Specific-Speed Centrifugal Pump for LRE

Taking low-specific-speed centrifugal pump as a research object,inner flow fields of the centrifugal pump are computed and analyzed by using the FLUENT software and the GAMBIT preprocessing software.Based on computation at results,appropriate optimization technigues are adopted to design a high-head high-speed super low-specific-speed centrifugal pump with high performances.Simulation results demonstrate that the optimization design method on the basis of the computation of the centrifugal pump inner flow fields is feasible and efficient.
