PERFORMANCE PREDICTION OF HORIZONTAL AXIS WIND TURBINE BLADE
India is a country of large population. As the population increases the demand for electricity is also increases. This demand of electricity is fulfilled by power plant. This power plant runs on the coal. This power plant produces the greenhouse gas. And this will affect the environment. Solution to this problem is renewable energy. In renewable energy wind is available free of cost. Wind is the problem of supply side management. Wind is the indirect form of solar energy. There are three methods of analysis (1) CFD analysis (2) analytical (3) experimentation. CFD analysis is the low cost method. There are mainly two types of turbine horizontal axis wind turbine and vertical axis wind turbine. Betz limit show that horizontal axis wind turbine produce more power than vertical axis wind turbine. If we carry out CFD analysis of wind turbine blade then it would be easy to determine different factors affecting the wind turbine blade while air is passing over it. From that we can find the value of Cland Cd and determine the forces acting on blade. From that calculation we can determine the power produced by the turbine. And also determine the angle of attack at which maximum power developed.
