This paper presents an open-access database of aerodynamic polars for a wide range of airfoils, relevant for wind turbine design and simulation. It includes lift, drag, and moment coefficients for multiple Reynolds and Mach numbers. Coefficients are computed with computational fluid dynamics for fully turbulent and free transition boundary layers, as well as a blend of the two. Beyond-stall extrapolation models are calibrated via a number of high-fidelity calculations at various angles of attack in separated flow.
