Abstract

The blades of large-scale wind turbines can obviously deform during operation, and such a deformation can affect the wind turbine’s output power to a certain extent. In order to shed some light on this phenomenon, for which limited information is available in the literature, a bidirectional fluid-structure interaction (FSI) numerical model is employed in this work. In particular, a 5 MW large-scale wind turbine designed by the National Renewable Energy Laboratory (NREL) of the United States is considered as a testbed. The research results show that blades’ deformation can increase the wind turbine’s output power by 135 kW at rated working conditions. Compared with the outcomes of the simulations conducted using the model with no blade deformation, the results obtained with the FSI model are closer to the experimental data. It is concluded that the bidirectional FSI model can replicate the working conditions of wind turbines with great fidelity, thereby providing an effective method for wind turbine design and optimization.
