Abstract
ABSTRACT Floating offshore wind turbines (FOWTs) are subject to the effects of waves, currents, and wind, which induced the platform's six degrees of freedom motion affects the aerodynamic performance of FOWTs. The yaw motion not only changes the incidence angle of the incoming flow, but also adds an angular velocity to the blades. Numerous studies have shown that winglets can increase the blade's total aerodynamic efficiency. This paper investigates the aerodynamic performance of FOWTs with fusion winglets during yaw motion. The findings demonstrate that the effect of changing frequency on wind turbine power is more significant at high amplitude conditions, when the frequency is increased from 0.1 Hz to 0.2 Hz with the amplitude of 6°, the average power growth rate of the wind turbine with winglets is 3.91% higher than the average power growth rate of the wind turbine without winglets.
