Investigation of aerodynamic performance and hydrodynamic motion of the semi-submersible FOWT based on IEA Task30 data
Accurate prediction of the time-dependent system dynamic responses of floating offshore wind turbines(FOWTs)under aero-hydro-coupled conditions is a challenge,as the study of wind turbine involves in the application of interdisciplinary knowledge,including the aerodynamic response of the entire system,the hydrodynamic response of the floating platform,the fluid structure coupling effect between waves and flexible structures,and the dynamic response of catenary lines.In this paper,computational fluid dynamics(CFD)method was used,supplemented by the dynamic fluid body interaction(DFBI)numerical analysis method.The simulation results were compared with the results of the International Energy Agency's Task 30 cooperation project(OC7)and previous literatures from other institutions,and the comparison results showed good consistency.In addition,the simulation results provide a new perspective in the potential field,forming a closed loop of mutual verification with previous engineering code simulations and pool testing results.
