résumé The paper presents the analysis of the interactions between the impeller and the vaned diffuser of a radial flow pump. Experimental data were obtained within one blade passage of a vaned diffuser using the 2D/2C PIV technique. The diffuser flow field was analyzed in various measuring planes in the hub to shroud direction, for seven relative impeller positions in the diffuser frame and in four different operating conditions. A post-processing procedure, based on statistical tools, was applied to the experimental results so as to validate their meaningfulness. The experimental results were compared to numerical data obtained with the help of CFX computer code.
