The files appended with the .cfluid can be visualized on Matlab Or MS Excel, The FTT may be computed directly from the velocity data using an FFT Function. The data used for this publication corresponds to the central probe (Probe1) in the x-direction (i.e. 5th column of the data set). TFD data the data is readily available to be viewed in Excel.
Figures 2, 6-11, 14-17, 19,20 and 22 were produced by visualizing the velocity field in Paraview. Simply click on the .foam files to visualise the data set. Note: Paraview must be installed.
