2.1 Film cooling
Film cooling is the introduction of a secondary (usually cooling) fluid at one or more points on a surface exposed to high temperature, to protect the surface itself not only near the injection point, but also downstream of it
Blades and nozzles, especially on their leading edges, lower and upper surfaces, and combustion chamber walls, are usually protected rather than cooled using this technique. Figure 16 shows a typical application of film cooling to a latest-generation nozzle: you can see the numerous injection holes in the end walls and profile of the blading, fed by air drawn from the...
