Hydraulic Design Method of Hyper-Normal Lower Specific Speed Propeller – Turbine Runner

Abstract:

The reasons are analyzed that propeller turbine cannot work properly under littler volume in some seasons, and then a scheme of capacity-decreasing improvement is put forward. Characteristics of design under hyper-normal factors are pointed out. Software of hydraulic design for lower specific speed axial flow runner blades has been developed by Visual Basic and AutoCAD basing on the method of singular point distribution. Finally, an example to demonstrate and explain its use is given in this paper.
