Cooling a quench aperture body of a combustor wall

An assembly for a turbine engine, the assembly comprising:

• a combustor wall including a shell, a heat shield and an annular body engaged with the shell and the heat shield;
• the annular body extending vertically through the combustor wall and at least partially defining a quench aperture along a centerline through the combustor wall, and a cooling aperture in fluid communication with the quench aperture;
• wherein at least a portion of the cooling aperture extends radially outward from the quench aperture relative to the centerline;
• wherein the annular body includes an inner surface and a shelf surface vertically recessed within the combustor wall relative to an exterior surface of the heat shield, the exterior surface of the heat shield configured to form a portion of a peripheral boundary of a combustion chamber of the turbine engine;
• wherein the annular body extends vertically to an exterior surface of the annular body and laterally to the inner surface that at least partially defines the quench aperture;
• wherein the inner surface and the shelf surface define a peripheral inner channel in the annular body, the shelf surface facing toward the combustion chamber;
• and
• wherein the exterior surface of the annular body is flush with an exterior surface of the shell, the exterior surface of the shell facing away from the combustion chamber.
