DNS Data for Turbulent Couette Flow
Three direct numerical simulations of fully developed flow at
different Reynolds numbers in a plane Couette 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 93, 220, and 500. 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.
When publishing results obtained using the
Couette flow fields provided here, we ask you to cite the source of
the data through the following publications
