DNS Data for Turbulent Channel Flow

Three direct numerical simulations of fully developed flow at different Reynolds numbers in a plane channel have been performed using the spectral numerical method of Kim, Moin and Moser (J. Fluid Mech. vol 177, page 133). The friction Reynolds numbers of the simulations are 180, 395 and 590. The lowest Reynolds number simulation exhibits severe low-Reynolds number effects, but the highest Reynolds number simulation does not. The details of the simulations are described in  Moser, Kim  and Mansour ( Phys. Fluids, vol 11(4) , page 943). Data may be added to the database from time to time, and corrections may be made. The data may be added to from time to time and corrections will be made if needed, a listing of the history of such changes is available.

 A comprehensive set of statistical data has been collected from these simulations and is available to be downloaded through the links below. It includes mean, Reynolds stress, skewness and flatness profiles, terms in the Reynolds stress transport equations, spectra and two-point correlations, and velocity and pressure probability density functions. The data is in a series of text files.
