Abstract

The numerical results presented in this paper demonstrate the ability of single vortex generators to reduce the cross passage secondary flow in a high-turning stator vane passage. The sensitivities of the induced vortex flow are determined in an initial study by varying the geometrical parameters. The visualisation of the flow patterns and the determination of the stator vane performance show that the efficiency and the working range can be increased by applying single vortex generators. The vortex generator design has to achieve a balance between the magnitude of vorticity induced to reduce the secondary flow phenomena and the additional losses associated with the produced vortex flow.
