Injection liquide dans les foyers de turboréacteurs : problèmes industriels et modélisation
Liquid injection in turboreactors combustors: industrial problems and modelling
This article presents a state of the art of the different technologies of fuel injectors used by Snecma in aeronautical engines. Traditionnal techniques of injection as well as concepts are described. The major role of the injector on the global performances of the combustor is pointed out. The experimental set up for the caracterisation of injection systems (granulometry, measurement of the spray angle, etc.) are presented. Finally, the authors will mention the munerical modelling developed for the simulation of the complex problem of the two-phase reactive flows in aeronautical combustors.
