A Critical Assessment of Wind Tunnel Results for the NACA 0012 Airfoil
Abstract
A large body of experimental results, which were obtained in more than 40 wind tunnels on a single, well-known two dimensional configuration, has been critically examined and correlated. An assessment of some of the possible sources of error has been made for each facility, and data which are suspect have been identified. It was found that no single experiment provided a complete set of reliable data, although one investigation stands our as superior in many respects. However, from the aggregate of data the representative properties of the NACA 0012 airfoil can be identified with reasonable confidence over wide ranges of Mach number, Reynolds number, and angles of attack. This synthesized information can now be used to assess and validate existing or future wind tunnel results and to evaluate advanced Computational Fluid Dynamics code.
