High-Reynolds Wind Turbine Airfoil Database

This open-access dataset provides high-fidelity aerodynamic polars for a wide range of wind turbine airfoils, computed using consistent CFD methodology. The database includes lift, drag, and moment coefficients across multiple Reynolds and Mach numbers. State-of-the-art post-stall extrapolation models are used. The databse includes coefficients computed with fully-turbulent and free-transition boundary layers. A blend of the free-transition and fully-turbulent coefficients is also included. The data is relevant for wind turbine design, modeling, and simulation, and reflects airfoil performance along the span of a representative offshore rotor. All simulations were performed using validated numerical methods and span a range of conditions typical for utility-scale offshore turbines. Airfoil geometries are included for ease of use. A detailed companion document describing the simulation methodology, validation, and structure of the dataset is available as part of the dataset. Please cite the Zenodo record when using this data.
