Abstract

Here we present the results obtained by TR PIV measurements focused on detailed flow analysis in the selected region. The investigated area was placed 3mm above the blades axis and 5mm far from the blade edge. The captured images were firstly analysed on the mean velocity distribution and the intensity of turbulence {UV} statistics. Here we used the time resolved technique for the experimental study of the flow field in the agitated vessel. The results of the application POD and ODP algorithm on the captured datasets uncovered the existence of unsteady structures in the area that was assumed to be stable. The existence of these structures is bringing a novel view on the mixing process.
