Boundary Layer DNS/LES Data

This directory contains integral quantities and velocity profiles for five selected streamwise positions, obtained from DNS and LES of a turbulent zero-pressure-gradient boundary layer. The data is free to use; please include a proper reference to the original publications.

In case of any questions, e.g. related to the data, or whether you wish for additiona data not presented here (e.g. integral quantities as a function of Re, additional wall-normal profiles of Reynolds stress budgets), please contact Philipp Schlatter, pschlatt@mech.kth.se.

A more or less concise description of the data and the underlying simulations is given in a recent presentation delivered at the 7th International Symposium on Turbulence and Shear Flow Phenomena (TSFP-7) in Ottawa, Canada, July 31, 2011: TSFP7-Presentation.pdf, and the corresponding proceedings article: 0i5p.pdf.

Visualisations:

• Isocontours of \lambda_2 (colour proportional to the wall distance) around approximately Re_\theta=1400; shown part is about 1/7th of the total domain length: jpg
• Recent poster (2009) (low res. pdf) (high res. pdf) (Gallery of Fluid Motion, APS DFD09).
• Three-dimensional visualisation of a turbulent boundary at high Re_\theta=4300, obtained by DNS: The visualised part has size 7000x4500 in plus units; shown are isocontours of negative lambda_2, coloured by height. The domain shown is about 7% of the complete computational box. orbit.mpg (Attention: 15MB), or at Youtube.
