Darrieus vertical-axis wind turbine performance enhancement approach and optimized design: A review

Wind energy is a clean and renewable energy source. The Darrieus vertical-axis wind turbine has the potential to be an efficient wind turbine with numerous applications. Various optimized designs aimed at enhancing the performance of Darrieus vertical-axis wind turbines are comprehensively reviewed, discussed, and summarized in this paper. First, we discuss output, self-starting, structural, and noise performance as the primary optimization objectives of the current Darrieus vertical-axis wind turbine. Second, the optimization design process for Darrieus vertical-axis wind turbines is reviewed by applying geometric parameters, shape characteristics, flow control technology, and cluster configuration as optimization objects and considering various optimization methods, such as experimental design optimization, response surface optimization, and proxy model optimization. Lastly, research suggestions and design guidelines for Darrieus vertical-axis wind turbine design optimization are presented. This work is intended to promote the high-quality development of wind power generation equipment and thus facilitate the realization of sustainable human development goals.
