Multicomponent Fuel Diffusion Flames: Flame Structure for Coupled Diffusion-Flame and Premixed-Flame Burning Regimes

43rd AIAA Aerospace Sciences Meeting and Exhibit, 2005
The analysis addresses some aspects of the extinction and the structure of diusion flames established by burning of two fuels. This analysis is asymptotically performed presuming one-global-step chemical reactions with large activation energies. By working with fuels with dierent activation energies, the structure is composed by two zones with dierent ...
