Research on Computer-Aided Design of Axial Turbine Blades with Ultra-Low Specific Speed

Abstract:

To solve the problem that hydropower stations equipped with propeller turbine are not able to work under small flow conditions in dry seasons, after analyzing the influencing factors, a rebuilding scheme for decreasing capacity to increase efficiency is proposed. The distribution of velocity circulation at the inlet and the outlet is researched in this paper. Some key technologies in computer-aided hydraulic design, including unfolded aerofoil converted to cylindrical surface and intelligent extension for curves, are solved. The proposed version is feasible and the composed CAD software is reliable and accurate.
