Abstract EN
This work is the final step of a research project that aims at evaluating the possibility of delaying the surge of a centrifugal compressor stage using a boundary-layer suction technique.
It is based on Reynolds-Averaged Navier-Stokes numerical simulations.
Boundary-layer suction is applied within the radial vaned diffuser.
Previous work has shown the necessity to take into account the unsteady behavior of the flow when designing the active flow control technique.
In this paper, a multislot strategy is designed according to the characteristics of the unsteady pressure field.
Its implementation results in a significant increase of the stable operating range predicted by the unsteady RANS numerical model.
A hub-corner separation still exists further downstream in the diffuser passage but does not compromise the stability of the compressor stage.
