摘      要：To simulate floating offshore wind turbine(FOWT)in coupled wind-wave domain via CFD method,the NREL 5MW wind turbine supported by the OC3-Hywind Spar platform is modeled in the STAR-CCM+ *** on the Reynolds-averaged Navier-Stokes(RANS)equations and re-normalisation group(RNG)k-εturbulence model,the rotor aerodynamic simulation for wind turbine is *** results agree well with the NREL *** advantage with the volume of fluid(VOF)method and dynamic fluid body interaction(DFBI)technology,the dynamic responses of the floating system with mooring lines are simulated under the coupled wind-wave sea *** free-decay tests for rigid-body degrees of freedom(DOFs)in still water and hydrodynamic tests in a regular wave are performed to validate the numerical model by comparing its result with the results simulated by ***,the simulations of the overall FOWT system in the coupled wind-wave flow field are carried *** relationship between the power output and dynamic motion responses of the platform is *** numerical results show that the dynamic response of wind turbine performance and platform motions all vary in the same frequency as the inlet *** platform motion,the power output of wind turbine is more sensitive than the thrust *** study may provide some reference for further research in the coupled aero-hydro simulation of FOWT.
