Optimization of Small Wind Turbine at Low Speed

Wind energy is an easily available renewable energy source. A turbine is a device that can convert wind energy into useful electrical energy. Wind energy is zero cost, affordable, reliable, and almost maintenance-free. That small wind turbine is applicable anywhere However, when sized properly and used in optimal working conditions, small-scale wind turbines could be a reliable energy source and produce low-cost valuable energy not only in rich countries but also in non-developing applications in locations that are far away from the main power in countries. Small-scale wind turbines are becoming a more area promising way to supply electricity in developing countries. The small-scale wind turbine blade has quite different aerodynamic behavior than their large-scale wind turbine. A small turbine can be installed for less energy requirement. Small wind turbines operating at low wind speeds regularly face the problem of less performance due to the profile of blades, angle of attack, twist angle, more drag of the blades. To overcome these problems we select an airfoil shape blade which is NACA 4412 which has a good result at a low speed. We are trying to modify it profile and design made using Creo software and taking some result by using Q-blade software.
