Abstract (en)

[origin: EP0745809A1] A mixer duct section (2) is positioned between the primary zone and the secondary stage and has vortex generators (200). The mixer section and vortex generators have passages through which mixed air (8) is injected into a main flow (4). A vortex generator has three flow surfaces one of which forms the roof surface, and the two other the side surfaces which are joined to the same wall segment of the duct. The roof surface with an edge running across the duct rests against the same wall segment (5,6) of the duct as the side surfaces. Longitudinally pointing edges of the roof surface are joined to the longitudinally pointing edges of the side surfaces protruding into the duct.
