Abstract

Wind energy is one of the clean renewable forms of that can handle the existing global energy crisis. A new design has been proposed for small-scale wind turbine laboratory with high power coefficients. The design used a three blades with Clark-Y airfoil smoothed and 15 segments on the blade. For twist and winglet, the horizontal axis wind turbine (HAWT) using Schmitz method and blended winglet. The turbine has been simulated using blade element momentum (BEM) method for two-dimensional analysis and Computational fluid dynamics (CFD) for three-dimensional analysis. The result shows that the effect of blended winglets on HAWT with winglet has an increasing performance because adding winglets capable of preventing the flow on the surface of tip blade from leaking power, This would reduce the intensity of tip blade rotor vortices and the corresponding lift-induced drag and also on the lower tip speed ratio (TSR), rotor with winglet has a larger starting torque. Therefore the effect of twist on the blade is adjusting a maximum angle of attack for airfoil toward relative velocity for increasing coefficient lift and reduces vortices on leading edge of the blade.
