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.
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.
