Aerodynamic investigation of horizontal axis wind turbine

Abstract

Wind energy is renewable, pollution free and abundant in the earth and it can reduce the dependency on fossil fuel for energy requirement. Wind energy is different form of solar energy, and it will available till sun is available. Large amount of wind energy can be continuously generated from wind source, that’s why large horizontal axis wind turbines are being installed to produce power, for more power extraction aerodynamic parameters associated with blade geometry and the material for blade are important. so in this paper we will discuss about the various aerodynamic characteristics which is important in terms of large power extraction with less material and cost expenditure.
