The aeroelastic and aero-acoustic behaviour of Darrieus-type vertical axis wind turbines (VAWT) individually and in wind farm formations will be investigated. Darrieus wind turbines were common in the 1970's but they were phase out due to problems with excessive vibrations. Advances in "smart" control systems and blade pitch control to suppress vibrations and the advent of composite blade structures have revitalized this conceptual design nowadays. In addition, the necessity of building offshore wind farms in deeper water to minimize the unavoidable visual and noise pollution near populated areas have pushed the industry to consider floating wind turbines. Horizontal axis wind turbines are not appropriate to floating installations due to its inherent stability problems.

将研究单独的 Darrieus 型垂直轴风力涡轮机 (VAWT) 以及风电场结构中的气动弹性和气动声学行为。 Darrieus 风力涡轮机在 20 世纪 70 年代很常见，但由于过度振动问题而被逐步淘汰。 “智能”控制系统和抑制振动的叶片桨距控制的进步以及复合材料叶片结构的出现，如今使这一概念设计焕发了活力。此外，为了最大限度地减少人口稠密地区附近不可避免的视觉和噪音污染，需要在更深的水域建设海上风电场，这促使该行业考虑浮动风力涡轮机。水平轴风力发电机由于其固有的稳定性问题而不适合浮动装置。
