Abstract
A combustor liner with an input end and an output end includes an annular inner wall and an annular outer wall. At least one of the inner wall and outer wall is three-dimensionally contoured. The inner wall and the outer wall form a combustion chamber with the contours creating alternating expanding and constricting regions inside the chamber causing combustion gases to flow in the circumferential and axial directions.
Claims20
A combustor liner with an input end and an output end, the liner comprising:
- an annular inner wall;
- and
- an annular outer wall;
- wherein at least one of the inner wall and outer wall is three-dimensionally contoured, and together the inner wall and outer wall form a combustion chamber with the contours creating alternating expanding and constricting regions inside the chamber causing combustion gases to flow in the circumferential and axial directions.
A generally cylindrical combustor to receive air and fuel at an input end, mix the air and fuel axially through the length of the combustor and distribute the mixture to a turbine at an output end, the combustor comprising:
- a combustor liner with an annular inner wall and an annular outer wall forming a combustion chamber, with at least one of the walls having three-dimensional contours creating alternating expanding and constricting regions inside the chamber to cause combustion gases to flow in the circumferential and axial directions;
- and
- a plurality of nozzles in an annular shape to distribute the fuel and air into the combustion chamber at the input end of the combustor.
A method comprising:
- injecting fuel and air into an annular combustion chamber between inner and outer liner walls of the combustion chamber at an input end;
- and
- creating localized mixing of the fuel and air in the combustion chamber with three-dimensional contours on at least one of the inner and outer liner walls around the circumference and axially through the length of the combustion chamber, with the contours forming alternating regions of expansion and constriction within the combustion chamber.
