Abstract
The Darrieus-type cross-flow water turbine has been proposed by the authors for utilizing undeveloped low head water power resources, but it is still lacking in available data for good hydrodynamic design. Here, effects of geometrical attitude of runner blade on hydrodynamic performance of turbine were investigated experimentally and discussed in comparison with theoretical results calculated by the method proposed in the preceding paper.Experimental results supported the theoretical consideration that the geometrical attitude of runner blade can be specified by single parameter of blade setting angle, and the best efficiency was obtained when the chord line of NACA 0030 aerofoil is in contact with the pitch circle tangentially at 40 % chord point. Comparing the calculated results with the measured data, the geometrical attitude of blade for the best runner efficiency was the same and the state of time variation in runner torque showed good similarity, while quantitative agreement was still insufficient.
