Abstract:
1. 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 the contoured wall is contoured around the circumference and contoured axially substantially through a length of the combustion chamber from input to output, 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 first set of the expansion regions circumferentially alternating with a first set of the constricting regions, the first set of the expansion regions and the first set of the constricting regions forming a first zone located at the input end; a second set of the expansion regions circumferentially alternating with a second set of the constricting regions, the second set of the expansion regions and the second set of the constricting regions forming a second zone located axially downstream from the first zone, the second set of the expansion regions circumferentially offset with the first set of the expansion regions and the second set of the constricting regions circumferentially offset with the first set of the constricting regions.
