| Abstract | Cooling air extracted from a gas turbine engine compressor is sent to nozzle vane cooling passage inlets 204, through the cooling passages 206, and to purge tubes 210 of a set of two or more vanes. A mixing chamber 214 formed between the purge tubes 210 in a diaphragm cavity receives fluid from the purge tubes 210 and directs it through exit passage(s) 216 formed through a wall of the mixing chamber 214 to a surface of the diaphragm 194. The exit passage(s) 216 can be inclined to induce a fluid velocity component substantially parallel to the surface and/or in a rotation direction of a turbine wheel. |
