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.

Overall Performance

This article predominantly focuses on the performance estimation of a small wind turbine blade when a dimple arrangement is made along its upper surface. The dimple arrangement is grooved at two locations: 0.25c and 0.5c, where c is the chord length of the turbine blade. A CFD analysis using the k-ε turbulence model is carried out on the selected blade sections NREL S823 and S822. The continuity and momentum equations are solved using ANSYS Fluent Solver to assess the aerodynamic performance of the proposed design. The effect of introducing a dimple on the blade surface has shown to delay the flow separation, with the formation of vortices. Further, the overall performance of the blade is simulated using GH BLADED and the results acquired are discussed.
