Abstract—This paper aims to present the Study on wind turbine and its aerodynamic performance. Rapid increase in global energy requirements has resulted in considerable attention towards energy generation from the renewable energy sources. In order to meet renewable energy targets, harnessing energy from all available resources including those from urban environment is required. This paper represents the study of wind turbine. There are two type of wind turbine Vertical axis wind turbine and Horizontal axis wind turbine that had been discussed on this paper. Vertical Axis Wind Turbines (VAWTs) are seen as a potential way of utilizing urban energy sources. Most of the research on the wind turbines constitutes condition monitoring and performance optimization of VAWTs under a constant velocity of air where the transient effects have not been accounted. The inconsistent behavior of the wind may change the nature of the flow field around the VAWT which could decrease its life cycle. This study is an attempt to use Computational Fluid Dynamics techniques to study and analyses the performance of a wind turbine under accelerating and decelerating air inlet velocity. A Horizontal-Axis Wind Turbine (HAWT) blade with 10,000 Watt power output has been designed by the Blade Element Momentum (BEM) theory and the modified stall model, and the blade aerodynamics are also simulated to investigate its flow structures and aerodynamic characteristics.
