Abstract:In order to solve the problem of the low efficiency of domestic water turbines, the development and research history of hose reel irrigator, and the early research of water turbine were reviewed. The hydraulic performance test, CFD analysis and improvement measures carried out by domestic researchers around JP75 and JP50 water turbines in the nearly five years were also reviewed. In addition, the impulse and radial flow water turbines commonly used in foreign countries were reviewed. The innovative research on an introductied water turbine with jet impulse inlet carried out by domestic researchers was emphatically described. The performance of this kind of water turbine was found to be much better than that of domestic water turbines based on experiment and CFD simulation, and the orthogonal test was used to analyze the influence of various parameters on the performance and the GA-BP optimization algorithm was used to conduct further optimization. Then an optimized water turbine model was obtained. CFD analysis and experiment proved that the internal and hydraulic performance of the optimized water turbine fully surpassed the foreign water turbine. Finally, the shortcomings of water turbine research were summarized, and improvement suggestions were proposed.
Keywords:hose reel irrigator  impulse water turbine  radial flow water turbine  internal flow  hydraulic performance  optimal design
