(2016) Lift enhancement of high angle of attack airfoils using periodic pitching. A database for reduced-complexity modeling of fluid flows. A., Lozano-Durán, A., Saxton-Fox, T., Parthasarthy, A., Biler, H., Jones, A. Keyword: fluid mechanics and aerodynamics Citation to related publication: Towne, A., Dawson, S., Brès, G. Users of these data should cite the papers listed below. 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. and 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. We recommend using the ‘airfoilDNS_example.zip’ file as an entry point to the dataset. 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. The dataset contains time-resolved snapshots of the velocity field, lift and drag coefficients, and airfoil kinematics spanning 40-100 convective time units. Discipline: Science and EngineeringĬreator: Towne, Aaron and Dawson, Scott Description: This dataset contains data from direct numerical simulations of two-dimensional stationary and pitching flat-plate airfoils at Reynolds number 100. (2020) Effect of transverse gust velocity profiles. (2021) Experimental investigation of transverse and vortex gust encounters at low Reynolds numbers. We recommend using the ‘airfoilEXP_example.zip’ file as an entry point to the dataset. Please see the ‘airfoilEXP_README.pdf’ file for more information. The dataset contains an ensemble of of the airfoil-gust encounter to account for variability in the gust profile, and each realization contains time-resolved force measurements and planar PIV velocity fields. Discipline: Science and EngineeringĬreator: Towne, Aaron, Jones, Anya, and Biler, Hulya Description: This dataset contains experimental measurements of a flat-plate airfoil passing through a large-amplitude transverse gust. (2019) Resolvent-analysis-based design of airfoil separation control. Citation to related publication: Towne, A., Dawson, S., Brès, G. We recommend using the ‘airfoilLES_example.zip’ file as an entry point to the dataset. Please see the ‘airfoilLES_README.pdf’ file for more information. The dataset contains 16,000 time-resolved snapshots of the mid-span and spanwise-averaged velocity fields. Creator: Towne, Aaron, Yeh, Chi-An., Patel, Het, and Taira, Kunihiko Description: This dataset contains data from a three-dimensional large eddy simulation of Mach 0.3 flow over a NACA 0012 airfoil at Reynolds number 23,000, which features a transitional boundary layer, separation over a recirculation bubble, and a turbulent wake.
