Due to the scarcity of fossil fuels, alternative energy has become necessary to meet the world's growing energy demands. A wind turbine is a rotary device that extracts wind energy and converts it to mechanical energy. The behavior and performance of wind turbines subjected to aerodynamic and ambient conditions must be studied in order to maximize the use of available wind energy. The NACA 0018 aero foil wind turbine blade is used to model vertical axis wind turbine rotors in this study. To improve rotor performance, the straight three bladed vertical axis wind turbine rotor is twisted to 45 degrees and 90 degrees. The weight of the rotor is significantly increased by twisting the rotor while maintaining the height and diameter of the rotors. Fiber reinforced composite materials are used to reduce the weight of the rotor without compromising its performance. To increase the strength-to-weight ratio, carbon, glass fibers, and epoxy resin were used in the fabrication. A straight and twisted three bladed vertical axis wind turbine rotor was CFD-analyzed in ANSYS-FLUENT and structurally analyzed in ANSYS for this purpose. Because of the limitations of experimentation, the wind loads on the blades were calculated using a computational fluid approach. The structural behavior of the rotor is obtained for a predetermined set of operating conditions after further application of these loads. The analysis' results are validated by comparing them to previously collected data.
