Résumé

The paper refers to the analysis of interactions between the impeller and the vaned diffuser of a radial flow pump tested in air. The vaned diffuser comes with two configurations: channel-type and cascade-type. The study deals with unsteady numerical simulations of the flow for complete 3D geometries of impeller and vaned diffusers in order to capture the full interaction effects. The task is conducted close to design operating conditions. The results focus on the flow pattern at the outlet part inside the impeller and influence from the diffuser vanes. Results from both diffuser configurations are compared and discussed. Results are also compared with the available PIV measurements.
