Abstract
A turbine engine having a compressor section, a combustion section having a combustor, and a turbine section in serial flow arrangement. The combustor includes a combustion chamber, at least one fuel injector, and a center body located within an air flow path of the fuel injector, where the center body has an internal fuel supply path. A vortex generator is provided on the center body and at least one fuel supply passage includes outlets that emit fuel into the air flow path for mixing the fuel with air in the air flow path.
Claims15
A turbine engine comprising:
- a compressor section, a combustion section including a combustor, and a turbine section in serial flow arrangement, the combustor comprising:
- a combustion chamber;
- a fuel injector having a body with a wall having an annular inner surface, wherein the annular inner surface of the wall forms an air flow path fluidly coupling an inlet with an outlet open to the combustion chamber;
- a center body located within the air flow path and having an internal fuel supply path, wherein the center body converges to a tip at a downstream end of the center body;
- a vortex generator provided on the center body downstream of the inlet and fluidly exposed to the air flow path, wherein the vortex generator and the center body are spaced from the annular inner surface of the wall;
- and
- at least one fuel supply passage having a fuel outlet emitting fuel into the air flow path for mixing the fuel with air in the air flow path;
- wherein the vortex generator has a radially outer surface that is angled radially inwardly and a radially inner surface that is angled radially outwardly, the radially outer surface and the radially inner surface converging towards an axial end of the vortex generator, the fuel outlet provided on at least one of the radially outer surface or the radially inner surface of the vortex generator.
A turbine engine comprising:
- a compressor section, a combustion section including a combustor, and a turbine section in serial flow arrangement, the combustor comprising:
- a combustion chamber;
- a fuel injector defining a centerline and having a body with a wall having an annular inner surface, wherein the annular inner surface of the wall forms an air flow path fluidly coupling an inlet with an outlet open to the combustion chamber;
- a center body located within the air flow path and having an internal fuel supply path, wherein the center body converges to a tip at a downstream end of the center body;
- a vortex generator provided on the center body downstream of the inlet and fluidly exposed to the air flow path, wherein the vortex generator and the center body are spaced from the annular inner surface of the wall;
- and
- at least one fuel supply passage having a fuel outlet on an exterior of the center body and emitting fuel into the air flow path for mixing the fuel with air in the air flow path;
- wherein the vortex generator has an outer surface that is angled radially inwardly towards the centerline and an inner surface that is angled radially outwardly away from the centerline, the outer surface and the inner surface converging towards an axial end of the vortex generator.
