Abstract : An axial flow compressor having a vortex generator system positioned upstream of a rotor with the height of the blades of the vortex generator system being greater than the running clearance of the rotor. of the vortex generator system has at least three blades for each of the rotor blades and is spaced from the rotor blades such that the leading edge of the rotor is a distance from the vortex generator system greater then ten times the height of the vortex generator blades and the trailing edge of the rotor blades is a distance from the leading edge of the vortex generator system less then eighty times the height the vortex generator blades. The spacing between the vortex generator blades is at least four times the height of the vortex generator blades. (Author)
