Abstract
A nozzle for a gas turbine engine that includes an air circuit, a water circuit, and a swirler that facilitate reducing erosion within the nozzle is described. The air circuit is formed by a first conduit that extends along the nozzle. The water circuit is formed by a second conduit that also extends along the nozzle and is radially inward from the first conduit. Each circuit is in flow communication with a discharge opening. An air swirler adjacent the discharge opening discharges air into water spray exiting the water circuit to facilitate evaporating the water to lower engine operating temperatures.
