1. A combustor liner for a combustor of a gas turbine, the combustor liner comprising:
an outer liner extending circumferentially about a combustor centerline; and
an inner liner extending circumferentially about the combustor centerline,
wherein, the outer liner and the inner liner define a combustion chamber therebetween, and
at least one of the outer liner and the inner liner includes a dilution flow assembly comprising, (a) an annular slot dilution opening, and (b) a dilution fence extending from an upstream side of the annular slot dilution opening to a downstream side of the annular slot dilution opening, and extending into the combustion chamber, the dilution fence including a plurality of dilution openings therethrough for providing a flow of an oxidizer through the dilution fence into the combustion chamber,
wherein the dilution fence includes (i) an upstream wall extending from the upstream side of the annular slot dilution opening into the combustion chamber and (ii) a downstream wall extending from the downstream side of the annular slot dilution opening into the combustion chamber, and
wherein the outer liner and the inner liner define a hot surface side adjacent to the combustion chamber, and a cold surface side adjacent to an oxidizer flow passage, and the downstream wall includes a deflector portion that extends from the cold surface side into the oxidizer flow passage.
