The objective of the paper is to design a more efficient model of a Vertical Axis Wind Turbine using advanced tools like Modelling, simulation and CFD analysis. It includes some advanced optimised design techniques. This concept is developed based on existing Savonius and Darrieus wind turbine models. To develop modified Savonius turbine and to analyze and compare its feasibility as an alternative method for harvesting wind energy at highest efficiency, in this paper, it is going to be replaced with a Savonius rotor blade with FIVE naca-0009 airfoils each side, which controls the motion of airfoils while the turbine rotor rotates. These Airfoils will be in closed condition when rotor is facing the direction of air stream and when the rotor blade comes in opposite direction to the wind, the three middle blades open by which the opposing Drag force will decrease inturn increasing the efficiency of VAWT.
