Abstract

In this paper a three dimensional viscous flow field in a Centrifugal Impeller with backswept and lean has been numerically analyzed using a commercial code (FLUENT) to understand the physics of complex real flow phenomena. The study was taken to investigate the flow interaction between impeller and vane diffuser for three different setting angles. It was shown at design point the flow at the exit of the impeller is uniform and the classical jet wake pattern is absent. At the intermediate plane between impeller inlet and exit and within vane diffuser channel the flow behaves like a potential flow. The stage analysis carried out using mixing plane formulation for three diffuser settings provided the optimum diffuser setting angle for maximum stage efficiency.
