The objective of this project is to construct a CAD model for tubercle wind turbine. Once the model is developed a complete CFD analysis of the flow pattern around the wind turbine will be carried out. The main objective of the study is to analyze and compare the performance of the tubercle wind turbine with the usual wind turbine. The power developed by both the turbine blades can be compared to support the use of tubercle. The tubercles are very effective for increasing the lift without stalling. The main objective of this project is to study the aerodynamic advantages of tubercle turbine blade. The effort will be to compare the obtained results with the straight blade of the same airfoil. This will provide insight into the advantages of using the tubercle blade. This technology being new the study is done numerically to study the overall effect of the tubercle.

The search for more efficient and sustainable renewable energies is rapidly growing. Throughout the years, wind turbines matured towards a lowered cost-of-energy and have grown in rotor size therefore stretched the role of composite materials that offered the solution to more flexible, lighter and stronger blades. The objective of this paper is to present an improved version of the preliminary optimization tool called Co-Blade, which will offer designers and engineers an accelerated design phase by providing the capabilities to rapidly evaluate alternative composite layups and study their effects on static failure and fatigue of wind turbine blades. In this study, the optimization formulations include non-linear failure constraints. In addition a comparison between 3 formulations is made to show the importance of choosing the blade mass as the main objective function and the inclusion of failure constraints in the wind turbine blade design.

Wind energy is an inexhaustible, an inexhaustible source of renewable and clean energy. Present due to the energy crisis and environmental protection and other issues, the use of wind more and more world attention. The wind turbine is the best form of wind energy conversion. Wind turbine wind turbine blades to capture wind energy is the core component of the blade in a natural environment to run directly in contact with air, with seagulls wings generate lift conditions are similar, so the gull wings airfoil and excellent conformation, with wind turbine blade design designed by combining the bionic blades. Through numerical simulation analysis found bionic blade aerodynamic performance than the standard blade aerodynamic performance has improved.

According to the design procedure of wind turbine blade, a design method that can make CAD software joint used was brought up. Wilson method was used to design and calculate the main data of blade. On this basis, the three-dimensional solid model of wind turbine blade could get by using and playing the function of different CAD software. This study provided a reference for the design of wind turbine blade and other similar complicated structures, which settles the basis for the further analysis of blade.

Turbine Blade Design

The objective of the project was to design a small wind turbine blade which is aerodynamically efficient and easy to manufacture. Preliminary aerodynamic analysis concluded NACA 63-425 to be the most efficient airfoil. Blade geometry was determined after calculating baseline geometric values for low drag which was then used to calculate power. Blade's structural integrity was studied using ANSYS® software. Tested results yielded that a single layer of E-fibreglass-epoxy is good enough to sustain the prescribed loads. The results were used to calculate the total weight of the blade which was then used to determine the start-up speed. Overall the project was successful in designing a wind turbine blade that produced 450 [W] of electrical power at 4[m/s] wind speed with the start-up speed of around 2[m/d]. The project fulfilled its objective which was to design a more effective wind turbine blade with manufacturability in mind.
