As the need for energy is rising, the generation capacity has to  be improved. While increasing the generation capacity, it is very important that the generation methods do not spoil the environment. Wind energy is a clean green and a renewable energy source, which was available in much concentrated form. The wind turbines which convert the available wind into useful power require a very high  wind speed in the range from 11m/s to 25m/s. The horizontal axis wind turbines are not effective in the low wind regimes and urban environment. The shape of the airfoil for the wind turbines is adopted from of the standard NACA profiles. The aerodynamic performance of these airfoils is not efficient. In this work, the section of the blade was mimicked from the fins of the hump back whale and analyzed for the aerodynamic performance characters such coefficient of lift  and coefficient of drag  using CFD Fluent software. A comparative analysis was made between a standard NACA 0012 blade section and a mimicked bumped edged NACA 0012 blade section. The angle of attack (AOA) was able be to increased upto 25° without of much stall and the increase in lift coefficient was 24%. Thus, these results of this work had created interest in modifying the blade profiles for the wind turbine operating in low wind regimes and urban environment.
