Wind energy is one of the major forms of renewable energy resources found abundantly which is widely used as an alternative energy. The energy can be converted into electricity by using Vertical Axis Wind Turbine (VAWT) and Horizontal Axis Wind Turbine (HAWT). The vertical axis wind turbine is highly used for domestic applications where the volume of production is low and efficiency is optimal while the horizontal axis wind turbine is widely for larger volume of production requires huge investment and the efficiency is high. This paper is focused on design and CFD analysis of Flat, Savonius, Helical, Involute Blade Profiles of same cross section by varying the aspect ratio (height, diameter and different wind speeds) of different blade profiles and the best efficient blade profile is identified using CFD analysis. Once the turbine blade profiles were developed they were tested for parameters like torque generated, power output, speed, tip speed ratioand the result shows the best blade profile which can be used to extract more power with a low wind speed between 1- 6 m/s (varriable) by CFD analysis. The analysis is made with and without frictionand with friction as a factors
