1. A combustor liner for a combustor of a gas turbine, the combustor liner comprising:
an outer liner comprising a plurality of outer liner segments connected together so as to extend annularly about a combustor centerline, each segment of the plurality of outer liner segments including at least one outer liner curved slot dilution opening therethrough in an outer liner dilution zone, each of the at least one outer liner curved slot dilution opening extending in a circumferential direction and having a constant width from a first circumferential end of the each of the at least one outer liner curved slot dilution opening to a second circumferential end of the each of the at least one outer liner curved slot dilution opening, and including an outer liner deflector wall adjacent to a downstream side of the each of the at least one outer liner curved slot dilution opening; and
an inner liner comprising a plurality of inner liner segments connected together so as to extend annularly about the combustor centerline, each segment of the plurality of inner liner segments including at least one inner liner curved slot dilution opening therethrough in an inner liner dilution zone, each of the at least one inner liner curved slot dilution opening extending in the circumferential direction and having a constant width from a first circumferential end of the each of the at least one inner liner curved slot dilution opening to a second end of the each of the at least one inner liner curved slot dilution opening, and including an inner liner deflector wall adjacent to a downstream side of the each of the at least one inner liner curved slot dilution opening,
wherein the each of the at least one outer liner curved slot dilution opening has a concave shape or a convex shape and is symmetrical with respect to a centerline axis of the each segment of the plurality of outer liner segments located between the first circumferential end and the second circumferential end, and
wherein the each of the at least one inner liner curved slot dilution opening has a concave shape or a convex shape and is symmetrical with respect to a centerline axis of the each segment of the plurality of inner liner segments located between the first circumferential end and the second circumferential end.
