Abstract

This study explores modifications to the blade airfoil cross-sections aimed at improving the efficiency of a 10 kW Bergey EXCEL horizontal axis small wind turbine. Specifically, the research focuses on altering the camber and thickness of the turbine’s baseline airfoil, designated as SG6043. Using advanced aerodynamic analysis tools like QBlade, the performance of the modified airfoils EY05-10 and EY08-9 is evaluated. The findings show that these modified airfoils achieve a higher lift-to-drag ratio compared to the baseline. These improved airfoils are then incorporated into the turbine’s blade geometry using the WT_Perf software. The enhanced turbine’s power generation capabilities are subsequently assessed with FAST (Fatigue, Aerodynamics, Structures, and Turbulence) version 8. Results reveal that at a wind speed of 15 m/s, the turbine with the modified blades produces 6.7% more power and 20.47% more annual energy than the original turbine.

优化效率，分析性能：水平轴小型风力涡轮机的强化翼面截面

本研究探讨了对叶片机翼截面的修改，旨在提高 10 kW Bergey EXCEL 水平轴小型风力涡轮机的效率。具体来说，研究重点是改变涡轮机基准翼面（代号为 SG6043）的外倾角和厚度。利用 QBlade 等先进的空气动力学分析工具，对修改后的翼面 EY05-10 和 EY08-9 的性能进行了评估。结果表明，与基准机翼相比，这些改进机翼的升阻比更高。然后，使用 WT_Perf 软件将这些改进后的翼面纳入涡轮机的叶片几何形状中。随后，使用 FAST（疲劳、空气动力学、结构和湍流）第 8 版对增强型涡轮机的发电能力进行了评估。结果表明，在风速为 15 米/秒的情况下，使用改进叶片的涡轮机比原来的涡轮机多发电 6.7%，年发电量多 20.47%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
