1. A gas turbine engine, the engine comprising:
a vane assembly comprising a flowpath wall,
wherein a fluid circuit is extended through the flowpath wall, and
wherein the fluid circuit defines a first inlet opening in fluid communication with a first cavity to receive a first flow of fluid through the fluid circuit, and
wherein the vane assembly comprises an ejector positioned at the fluid circuit,
wherein the ejector defines a second inlet opening in fluid communication with a second cavity to receive a second flow of fluid through the ejector and into the fluid circuit, the second cavity being fluidly separated from the first cavity, the second flow of fluid having a higher pressure and a higher temperature than the first flow of fluid,
wherein the ejector comprises a nozzle positioned downstream of the second inlet opening relative to the second flow of fluid toward the fluid circuit, and
wherein the nozzle is configured to urge the first fluid flow through the fluid circuit by ejecting the second flow of fluid from the second inlet opening through the nozzle into the fluid circuit.
