In the present study, an optical system-operated PIV technique was employed to obtain the time-wise variations of both the velocity-vector and vorticity distributions near an interference knot point inside a diamond-shaped cylinder bundle. In conclusion, the micro PIV measurements have for the first time disclosed the location and flow process characteristics of the interference kont point as the edge-tone source.
