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.

Adrian, "PIV Study of Small-Scale Flow Structure around a Rushton Turbine," AIChE Journal, V. 47, No. 4, p. 766-778, 2001.
