PIV Data: Small-Scale Flow Structure around a Rushton Turbine

The data are provided in a simple columnar ascii format (*.txt). Each row of the data represents one velocity vector. The first two columns correspond to radial position r and axial position z respectively, in physical units (mm). The third and/or fourth columns correspond to either radial and axial velocities, normalized turbulence intensity, or vorticity.  All dimensional quantities are given in units of millimeters and seconds.  The data files also include a one-line header so they can be immediately read into Tecplot.

For a complete listing of filenames and column labels, see p.778 (Appendix) of Sharp, K. V. and R. J. Adrian, "PIV Study of Small-Scale Flow Structure around a Rushton Turbine," AIChE Journal, V. 47, No. 4, p. 766-778, 2001.  This table, along with a short summary of definitions and notation, may be found in the following pdf file: Sharp_Rushtondata .
