A., Lozano-Durán, A., Saxton-Fox, T., Parthasarthy, A., Biler, H., Jones, A. the attainable lift-to-drag ratio) compared to performance of airfoils at higher Reynolds numbers. Airfoil performance at low Reynolds numbers is generally characterized by low aerodynamic performance (i.e. Users of these data should cite the papers listed below. Reynolds numbers significantly below 500,000 1. The paper introduces the flow setup and computational methods, describes the available data, and provides an example of how these data can be used for reduced-complexity modeling. The airfoil section is the quintessence of a wing or lifting surface and, as such, occupies a central position in any design discipline relating to fluid. The dataset is part of “A database for reduced-complexity modeling of fluid flows” (see references below) and is intended to aid in the conception, training, demonstration, evaluation, and comparison of reduced-complexity models for fluid mechanics.Use these graphs to find for a Reynolds number of 5.7 x 106 for both the smooth and rough surface cases: 1. The above input will run the airfoil through angles of attack from -15 to 15 degrees at a Reynolds. Otherwise, they default to the value specified as constant when the database was generated. We recommend using the ‘airfoilDNS_example.zip’ file as an entry point to the dataset. The graphs below show the aerodynamic characteristics of a NACA 2412 airfoil section directly from Abbott & Von Doenhoff., i.e., the lift coefficient, the drag coefficient, and the pitching moment coefficient about the 1/4-chord axis. For ‘database’ airfoils, ‘Mach’ and ‘Rey’ default to the average value in the database, if the database is dependent on that variable. This database makes use of actual wind tunnel data of 74 different airfoils rather than theoretical predictions which are often inaccurate at low Reynolds numbers. Please see the ‘airfoilDNS_README.pdf’ file for more information. All data are stored within hdf5 files, and a Matlab script showing how the data can be read and manipulated is provided. Cases include a stationary airfoil and eight different pitching frequencies. We will use the same airfoil (NACA 4412), but because we reuse this data for the validation in the introductory tutorial, we will pick out a Reynolds number. The dataset contains time-resolved snapshots of the velocity field, lift and drag coefficients, and airfoil kinematics spanning 40-100 convective time units.
