Abstract

Among the offshore floating wind turbine software packs, the blade element momentum theory (BEM) and generalized dynamic wake (GDW) model are widely used. A free vortex wake model has been coupled to FAST v7 to do a comparative dynamic analysis between using the BEM theory and GDW method on offshore floating wind turbine. The verification test on the free-wake model has been performed according to the NREL VI experiment in steady and yaw conditions. To analyze the unsteady aerodynamics of floating wind turbine, the OC3 spar type wind turbine has been used to do simulations. The global performances on both the rotor and the platform and their interactions are shown and discussed.
