The present paper deals with the selection of blade profile for VAWTs which is to be installed in the low potential zones like central India where the mean velocity of the air is around 4 km/hr. These amplitudes are quite low for commissioning the wind turbine in that region, whereas we need around 10 km/hr speed for the installation of wind turbines. Both experimental and numerical analysis has been carried out for the three selected airfoils recommended by NASA. We are working with the three optimized profiles NACA 0012, NACA 0015 & S2027. The results show a good correlation with the existing literature. Airfoil profile S2027 has been chosen which best suits our condition.
