Simulation numerique d’un écoulement dans une roue d’un compresseur centrifuge

Abstract

This work is a numerical investigation in three dimensions of the unsteady flow in a centrifugal compressor wheel, which it shows the influence of the mass flow rate and rotational speed on its performances. The study was based on examining the impact of their modeling on the prediction of the flow in centrifugal compressors. It was performed under a viscous turbulent aerodynamic approach using the( KW SST) model, we end this by a validation with another turbulent model ( k-є ) in light of the comparison.
