ABSTRACT:
A wind turbine is a rotary device that extracts energy from the wind. Wind energy has been shown to be one of the most viable sources of renewable energy. With current technology, the low cost of wind energy is competitive with more conventional sources of energy such as coal. Rotor blade is a key element in a wind turbine generator system to convert wind energy in to mechanical energy. Most blades available for commercial grade wind turbines incorporate airfoil shaped cross sections. These blades are found to be very efficient at lower wind speeds in comparison to the potential energy that can be extracted. Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. Computers are used to perform the calculations required to simulate the interaction of liquids and gases with surfaces defined by boundary condition. In this paper, CFD analysis of wind turbine blade, a complete drawing, and details of sub-system are carried out.
INTRODUCTION:
WIND turbine has been getting its attention as one of the most viable alternative power media. Renewable energy from natural resources like wind, water and sun has found new emphasis in recent years due to the impending depletion of the non-renewable energy sources like coal and oil and ever increasing demand for energy due to rapid growth of the global industrialization. Consequently, the search for new and efficient methods to harness these available resources has prompted a fresh look at the existing technologies. Computational Fluid Dynamics (CFD) has grown from a mathematical curiosity to become an essential tool in almost every branch of fluid dynamics,
