1. A gas turbine engine combustor comprising:
a liner defining at least in part:
a combustion chamber,
a first side exposed to the combustion chamber,
a second side opposite the first side,
a plurality of cooling holes extending from the second side to the first side, and
a dilution hole extending from the second side to the first side,
wherein the dilution hole is larger in diameter than each of the plurality of cooling holes,
wherein the liner comprises an airflow feature on the first side of the liner adjacent to the dilution hole, a mass of which extends into the combustion chamber to increase a cooling of the liner,
wherein the combustion chamber defines an airflow direction over the dilution hole on the first side of the liner and a transverse direction perpendicular to the airflow direction,
wherein the airflow feature is positioned adjacent to the dilution hole along the transverse direction,
wherein the dilution hole of the liner is a first dilution hole, wherein the liner further defines a second dilution hole spaced from the first dilution hole along the transverse direction, and
wherein the airflow feature is positioned between the first dilution hole and the second dilution hole.
