Experimental Investigations and CFD Simulations of the Blade Section Pitch Angle Effect on the Performance of a Horizontal-Axis Hydrokinetic Turbine

ABSTRACT: Three twisted blades of a 1 kW prototype hydrokinetic turbine were designed based on the Blade Element Momentum (BEM) theory with a tip speed ratio of 6.25; water velocity of 1.5 m/s; angle of attack and pitch angle of 5 and 0°, respectively; a power coefficient of 0.4382 and a drive train...
