Abstract

A nozzle includes a nozzle body and a cavity defined at least in part by the nozzle body. A plenum extends through the nozzle body into the cavity. At least one passage through the plenum provides fluid communication between the plenum and the cavity. Orifices through the nozzle body and circumferentially spaced around the nozzle body provide fluid communication through the nozzle body. A method for cooling a face of a nozzle having a nozzle body that defines a cavity includes flowing a fuel through the cavity and inserting a plenum through the nozzle body into the cavity. The method further includes flowing a fluid through the plenum so that the fluid impinges on the face of the nozzle to remove heat.
