اثر ناپایداری نکته بر عملکرد آیرودینامیکی توربین بادی افقی محور

Tip loss corrections are an important factor in Blade Element Momentum (BEM) theory when determining optimum blade design for maximum power production. This paper presents the optimal tip design using the new tip loss correction. A semi-analytical solution was proposed to find the optimum rotor considering Shen’s new tip loss model. The optimal blade geometry is obtained for which the maximum power coefficient is calculated at different design tip speed and glide ratio. Our simulation is conducted for S809 rotor wind turbine blade type, produced by National Renewable Energy Laboratory (NREL).
