...Saif Al Hamad; Omar Habash; Alaa Hasan; Ryoichi S. Amano In this work, the effect of the inner opening ratio on the J-shaped airfoils aerodynamic performance was studied and documented for symmetrical airfoils. Three different airfoil thicknesses were investigated: small (NACA0008), medium...

... investigation of the effectiveness of a vortex trapping cavity (VTC) on the aerodynamics of the National Renewable Energy Laboratory phase VI wind turbine. First, simulations are conducted on the S809 profile to study the fluid flow compared to the airfoil with the redesigned VTC. Second, the blade is simulated...

...Mehmet Numan Kaya; Faruk Köse; Oğuz Uzol; Derek Ingham; Lin Ma; Mohamed Pourkashanian The aerodynamic shapes of the blades are still of high importance and various aerodynamic designs have been developed in order to increase the amount of energy production. In this study, a swept horizontal axis...

...Amin A. Mohammed; Hassen M. Ouakad; Ahmet Z. Sahin; Haitham M. S. Bahaidarah Momentum models or streamtube models represent one of the fundamental approaches in modeling the aerodynamics of straight bladed vertical axis wind turbine (SB-VAWT) of Darrieus type. They are based on momentum (actuator...
