Abstract
The renewable energy is a promising field, which shows a lot of potential for future energy solutions. The design of the blade shows a lot effects on the efficiency of the wind turbine, and the design parameters governs the performance characteristics. This paper addresses a number of innovative blade designs that was developed by alterations made to the existing conventional straight blade. These blades were extensively studied using computational fluid dynamics (CFD) software, and showed promising results, which was the motive behind this study. We are designing an experiment to study small scale wind turbines, which will enable us to gather data that will explain some differences in power and torque output. These steps will help us to come to a better understanding of some aerodynamic aspects that will impact the performance of each individual blade design. The comparing criteria for this study was the torque generation at the axes of rotation, which can be translated to several parameters, such as energy output, using some theoretical basis equations.
