Abstract: One parametric design method is suggested for the convenience of blade design operation and shape control, which is firstly used in the design process of hydraulic energy recovery turbine. Firstly, the theoretical models of parametric design is established based on the derivation of meridional streamline integral equations, meanwhile the flow chart and calculation table are offered. Then the characteristics of hydraulic energy recovery turbine are analyzed. Moreover, the process of parametric design is carried out for a case of hydraulic energy recovery in water distribution network. Finally, the flow field and performance are studied by numerical simulation. The curves of wrap angle and setting angle are obtained in the process of parametric design, after that the velocity moment at blade outlet was changed by control of wrap angle distribution. The flow field is uniformly and maximum numerical predicted efficiency has reached 93.6%. Moreover the feasible of hydraulic energy recovery turbine is verified by test and the operating efficiency has reached 88.3%. The conclusions can provide guidance in the design process of hydraulic energy recovery turbine.
