1. A seal assembly for a gas turbine engine, the gas turbine engine defining a central axis extending along an axial direction and the gas turbine engine comprising a rotating shaft extending at least partially along the axial direction, the seal assembly comprising:
a first component coupled to a fixed structure or drivingly coupled to the rotating shaft of the gas turbine engine;
a rotating component drivingly coupled to the rotating shaft of the gas turbine engine, wherein the first component and rotating component define an annular gap therebetween; and
at least one flange extending from at least one of the first component or the rotating component, the at least one flange comprising:
a base; and
an external surface that extends linearly from the base toward a tip of the at least one flange, wherein the external surface extends into the annular gap;
wherein the at least one flange defines an inlet port on the external surface fluidly coupled to an outlet port at the tip,
wherein the at least one flange extends from the rotating component and the inlet port is positioned on the external surface at a location that is radially spaced from the base or wherein the at least one flange extends from the first component and the inlet port is positioned on the external surface at a location that is radially spaced from the base, and
wherein the at least one flange forms a seal within the annular gap.
