DNS Data for Turbulent Channel Flow

Four direct numerical simulations of fully developed flow at different Reynolds numbers in a plane channel have been performed with POONGBACK code which uses 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, 550, 1000, 2000 and 5200. The data may be added to from time to time and corrections will be made if needed.

A comprehensive set of statistical data has been collected from these simulations and is available. It includes mean, Reynolds stress, terms in the Reynolds stress transport equations, etc. The data is in a series of text files.
