The use of wind based energy is quickly expanding over the planet. The goal of this study is to use computational methods of fluid dynamics to develop a novel model of VAWT including Windbooster for various rotor blades like two, three, and four blades in order to enhance effectiveness. CAD modelling approaches of vertical axis wind turbines including and excluding booster are created. Including all vertical axis wind turbine blade designs including and excluding booster, torque, power, and Coefficient of performance are compared.The performance of three blades on the basis of mechanical properties includingi wind amplifier is 29.9% greater than two blades using wind amplifier, and four blades using wind amplifier is 21.5 percent greater than three blades using wind amplifier, according to the findings. Because the mechanical energy created by a four-blade wind booster wasn't as great as it is including three blades, VAWT employing three-blade wind booster seems to be more effective than VAWT with a two- or four-blade wind booster. For improved mechanical durability, VAWT with three-blade wind amplifier is recommended.
