“…According to the mechanism of obtaining stability, the floating foundation platforms are mainly divided into three types: semi-submersible type, Tension Leg Platform (TLP) type, and spar type (Jonkman, 2010a;Matha, 2010;Karimirad and Moan, 2012a). Examples of semi-submersible wind turbine concepts include WindFloat and Fukushima-Forward (Duan and Li, 2016). Blue H TLP and Wind Star TLP (Zhao et al, 2016b) are examples of the TLP-type FOWT, while Hywind (Nielsen et al, 2006) and Goto-FOWT (Duan and Li, 2016) belong to the spar family.…”

“…The experimental results of nacelle motions and anchor loads were compared with the numerical results of the in-house code 3Dfloat (Jonkman, 2010a) and ANSYS, which showed good agreement. More recently, Duan et al (2016) performed a 1:50 scale model test of OC3 spar-type FOWT at the State Key Laboratory of Ocean Engineering (SKLOE) at Shanghai Jiao Tong University (SJTU). In their tests, the rotor was allowed to rotate freely with the wind speed.…”

“…They are mainly used in far-sea areas over 200 m from shore with water depths greater than 50 m [3]. Unlike fixed offshore wind turbines, FOWTs can be installed in deep-water areas with abundant wind resources and harsh offshore climate conditions, making them more economically viable [4]. The movements of the wind, waves, and currents cause the FOWT platform to move in the direction of six degrees-of-freedom (6-DOF), which can greatly impact the aerodynamic performance and wake characteristics of wind turbine [5].…”

The floating offshore wind turbine platform is subject to six degrees‐of‐freedom motions due to the influence of wind, waves, and currents. To examine the impact of pitch motion on the wake characteristics of offshore wind turbines, this research focused on investigating the wind turbine wake under pitch motion using the RANS k−ε$k - \varepsilon $ model and the overset grid technique based on OpenFOAM. The simulation accounted for wind shear flow conditions and simplified the movements of the six degrees‐of‐freedom of floating platform. Results showed that the wind turbine wake recovery rate increased with pitch motion, and that the recovery rate increased with the frequency and amplitude of the pitch motion. The wind velocity recovery rate of near‐wake was sensitive to small amplitudes, while the far‐field wake was unaffected. When the amplitude was larger, pitch motion accelerated the wind velocity recovery rate in all wake areas, leading to more pronounced diffusion. These findings provide insight into the mechanism of wake generation and diffusion under pitch motion in floating offshore wind turbines and offer a basis for enhancing the wake deficit model of floating offshore wind farms.
