Modeling and Comparative Performance Analysis of Different Bladed Vertical Axis Wind Turbine (VAWT)

Collective effort on energy sector mainly renewable energy, especially Wind Turbine design and development is of major concern. Nowadays, due to the energy crisis, the Horizontal Axis Wind Turbine (HAWT) is most commonly used due to its high height. Because we can attain high wind speeds and that results in self-starting capabilities of HAWT. Nevertheless, Vertical Axis Wind Turbine (VAWT) titled Savonius Wind Turbines have many advantages over HAWT and Darrieus VAWT.This research aims to model, design and analyze the performance of different bladed Vertical Axis Wind Turbine (VAWT) by considering different design parameters. Different bladed Savonius type VAWT were taken as testing objects and their performance was analyzed with respect to velocity and number of blades in terms of RPM, voltages, torque, and power. The results concluded that three bladed VAWT is much better than other different bladed VAWTs.
