Turbulent three-dimensional diffuser DNS database

This directory contains velocity profiles and mean fluctuations obtained from the DNS by Ohlsson et al. (JFM 650 307 - 318). This simulation was designed to match the experiment by Cherry et al., 2008, IJHFF 29(3). The data is given at the same streamwise and spanwise locations as during the 14th ERCOFTAC SIG15 Workshop on Turbulence Modelling, held in Rome, September 2009.

Except for these quantitites (Cp, streamwise velocity and rms contours, profiles of all mean velocity components, normal and shear stresses, turbulent kinetic energy), the full Reynolds stress budgets will be available in the future.

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 additional data not presented here, please contact Johan Malm, johan@mech.kth.se.
