Structure Optimization of Wind Turbine Blade with Winglet using CFD

Abstract

The wind turbines have restriction on increasing its rotor diameter. Winglets are angled extensions or vertical projections at a wing's trail and are commonly utilized on commercial aircraft in combination with flat airfoils to minimize induced drag and increase lift. Introducing a winglet to the cutting edge of the turbine blade enhances the power generation without extending the intended rotor area. For the aeronautical industry and especially for high-performance sail planes, the winglet structure has been thoroughly examined. Because winglets have been shown to decrease drag and increase wind turbine rotor blade aerodynamic efficiency, it is major to realize and evaluate the method of performance and design enhancement used by previous researchers for this application. It provides a good description and concepts for handling the design process for the application of the wind turbine. The objective of the project is to evaluate turbine blade flow dynamics with winglet and to enhance the efficiency of its physical dimensions. CFD analysis would be go through by altering its physical size and shape with the target of realizing augmented power.
