Summary:

Since the completion of the DNW test, HART II partners have put forth significant efforts to derive vortex properties from the measured data. These properties include vortex center, rotation angles of the vortex axis in the PIV measurement plane, maximum vorticity, core radius, and swirl velocity. Differences among the partners' results were found for some of these vortex properties, which required more effort to assess the physical significance of the differences. This was because the derived vortex properties were an integral of all the sub-processes in the complex PIV data analysis procedure, and more information was needed to resolve the differences in vortex properties. The objectives of this report are to discuss and summarize the parameters and techniques that could contribute to these differences. The detailed comparisons in this report have helped establish a strong foundation for a PIV data analysis methodology in determining vortex properties.
