EXPERIMENTS ON HYDRODYNAMIC PERFORMANCE OF WEIS-FOGH-TYPEWATER TURBINE

This study examines the hydrodynamic characteristics of the Weis-Fogh-type water turbine by measuring the forces in the U and V directions on the wing (NACA0010 airfoil). The distance from the trailing edge of the wing to the wing shaft (r(p)), water channel width (h), and maximum opening angle (alpha) are important design factors that were selected as the experimental parameters. The maximum average efficiency and average power coefficient of this water turbine for a single wing were 40% and 0.6, respectively, at alpha = 40 degrees, h = 1.5C, and U/V = 2.0.
