Aerofoil dipole noise due to flow separation and stall at a low Reynolds number
International Journal of Heat and Fluid Flow, special issue: 11th International Symposium on Turbulence and Shear Flow Phenomena – TSFP11.

This dataset contains:
The ACSII (.dat) files and binary Tecplot (.plt) data files that were used to generate the figures in the paper.
The Tecplot layout (.lay) files which can be used to visualise the plots.
The graphic software Tecplot 360 EX can be downloaded for free (fixed-period trial version) from:
http://www.tecplot.com/my/free-trial-software/tecplot-360/
The archive file MainFigures.7z contains the data for the figures 1,2,4,5,6,7,11,12 and 13, data for figures 3,8,9,10 are uploaded separately.

The title of the files corresponds to the figure numbers in the paper.
