Aerodynamic Analysis Of Horizontal Axis Wind Turbine Blade

摘要

Wind energy has been shown to be one of the most viable sources of renew able energy. With current technology, the low cost of w ind energy is competitive with more conventional sources of energy such as coal. Most blades available for commercial grade wind turbines incorporate a straight span-wise profile and airfoil shaped cross sections. For the testing of aerodynamic efficiency wind turbine blade, w ind tunnel test is carried out. In this paper we select NACA 4420 airfoil for analysis. CFD Analysis of HAWT Blade is carried out at various blade angles with help of ANSYS CFX and comparing that result with experimental results. HAWT efficiency is highly depends on the blade profile and its orientation. We can find optimum angle at w hich HAWT gives constant output
