摘要

The complex and dynamic nature of the marine environment significantly impacts the operational characteristics and stability of floating wind turbines. The floating platform located offshore has the ability to move in six dimensions, leading to more complex unsteady aerodynamic characteristics for floating offshore wind turbines (FOWTs) when compared to their fixed-bottom equivalents. This research employs advanced fluid dynamics simulation methods to examine how combined surge and pitch movements—two critical components of 6-DOF motion—influence turbine aerodynamic efficiency and wake patterns. Analytical findings reveal that synergistic surge-pitch motion generates substantially greater peak thrust and energy output than isolated motion patterns. The coordinated movement mechanism not only improves overall aerodynamic effectiveness, but also effectively reduces performance degradation typically observed in separate motion conditions. Additionally, the study examines the influence of periodic parameters on coupled motion, showing that velocity stability during coupled motion lies between that of the individual motions. Surge motion primarily influences velocity in coupled scenarios, and the interaction between surge and pitch motions increases load complexity while moderately improving velocity stability.
