Resumé

Wind energy is the major renewable energy source available easily in abundance. It has become more popular than other renewable energy sources because of its compatible cost with conventional energy sources. The demand of small wind turbine in the market with a reliable, durable and more efficient technology is increasing. Blade is the key element of wind turbine. Performance of wind turbine blade mainly depends on its airfoil. In the present work, new airfoil is developed with the aim of performance improvement of wind turbine. Two different airfoils are designed for root sections and tip sections. Blade Element Momentum theory is used in designing of the small wind turbine blade. The numerical analysis of blade airfoil is carried out by Q-Blade software. The results obtained are compared with NACA 2412 and SG 6042 airfoils. In addition, performances of blades made with individual airfoil are compared by using Q-Blade software. These comparisons are made by keeping the length of the blade and chord lengths of various airfoils constant. The new airfoils have shown better performance than NACA 2412 and SG 6042 airfoils.Keywords: Q-Blade, wind turbine blades, airfoilCite this Article:Kale SA, Birajdar MR, Sapali SN, Numerical Analysis of New Airfoils for Small Wind Turbine Blade.
