Abstract

The accurate modelling of secondary-flow dynamics is a key aspect of reliable performance predictions for turbomachinery. This is due to the effect of secondary flow on the aerofoil boundary layers, as well as the overall energy budget. In this paper, we assess the predictive performance of a vortex-reactive turbulence-model extension using integral performance data of a multi-stage compressor test rig. The model extension provides a more accurate prediction of multi-stage compressor characteristics, especially if cavities and squealer tips are considered. This is achieved by mitigating an underprediction of near-choke mass-flow rates, and of the total-pressure ratio and isentropic efficiency near stall. The analysis shows that this is achieved by affecting the formation and propagation of secondary flow.
