Abstract

Accurate predictions of aerodynamic performance and near wake expansion around Horizontal Axis Wind Turbine (HAWT) rotors is pivotal for studying wind turbine wake interactions and optimizing wind farm layouts. This study introduces a novel engineering model centered on stall delay correction to enhance the precision of the Actuator Disk Method (ADM) predictions in both aerodynamic performance and near wake expansion around HAWT rotors. The model is developed based on a comprehensive study of the 3D lift coefficient evolution over the rotor blade, incorporating a shift parameter that considers both stall angle detection and radial decrement. The proposed approach demonstrates remarkable agreements, showcasing discrepancies as low as 7% for both loads and axial wake predictions. These quantifiable results underscore the effectiveness of the model in capturing intricate aerodynamic phenomena. Looking forward, the success of this approach opens avenues for broader applications, guiding future research in wind energy towards improved simulation accuracy and optimized wind farm designs

改进风力涡轮机应用性能预测的工程方法：与完整纳维-斯托克斯模型和实验测量结果的比较

准确预测水平轴风力涡轮机（HAWT）转子周围的气动性能和近尾流扩展对研究风力涡轮机尾流相互作用和优化风电场布局至关重要。本研究介绍了一种以失速延迟修正为中心的新型工程模型，以提高推杆盘法（ADM）对 HAWT 转子周围气动性能和近尾流扩展的预测精度。该模型是在对转子叶片上的三维升力系数演变进行全面研究的基础上开发的，其中包含了一个同时考虑失速角检测和径向递减的偏移参数。所提出的方法显示出显著的一致性，在载荷和轴向尾流预测方面的差异低至 7%。这些可量化的结果凸显了模型在捕捉复杂空气动力现象方面的有效性。展望未来，这种方法的成功为更广泛的应用开辟了道路，并将指导未来的风能研究，以提高模拟精度和优化风电场设计。

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.
