Abstract (en)
A lobed injector finger for a burner or a mixer of a gas turbine comprises a leading edge (23), a lobed trailing edge (24), a first and a second corrugated surfaces (40a, 40b) defining an airfoil cross section and converging in the trailing edge (24), a plurality of nozzles (27) located at the trailing edge (24) for injection of oil or fuel or carrier air in the burner or mixer, and a plurality of vortex generators (42) projecting from a suction side of lobes (28) defined by the first and second corrugated surfaces (40a, 40b) and positioned from the nozzles (27) to reduce flow separation and/or influence the location of a separation bubble.
