Aerodynamic behavior of the NREL 5-MW floating offshore wind turbine

The flowfield around the rotor blades of a wind turbine may be quite complex to predict, due to the occurrence of several aerodynamic phenomena. It is all the more true for floating offshore wind turbines (FOWT), for which the six rigid-body motions of the floating platform can induce blade/wake interactions. Therefore conventional numerical approaches for wind turbine applications, such as BEM, may be questionable for an accurate prediction of floating wind turbine aerodynamic loads. The aerodynamic behavior of the NREL 5-MW subjected to a prescribed pitch motion is here investigated based on CFD simulations. 3D URANS computations with elsA CFD solver () Co-processing with Cassiopee () Most of this work was granted access to the HPC resources of CINES under the allocation2018-A0032A10280 made by GENCI.
