摘要

Diffusion flames of CH2-type hydrocarbon fuel in air boron in air and aluminum in the reaction products of ammonium perchlorate with solid-propellant hydrocarbon binder are examined theoretically. From simple chemical equilibrium calculations over a very wide range of fuel/oxidizer ratio, necessarily important intermediate reaction species are identified. If the fuel is a gaseous jet and if reaction kinetics are essentially instantaneous so that turbulent mixing is controlling the equilibrium calculations can be readily expressed in terms of flame geometry. If the fuel is a condensed-phase particle, simple spatial representation of equilibrium mole fractions reflects some distortion of the actual case where different species can be ex¬pected to have different molecular diffusivities and different reaction rates. Nevertheless, an important contribution to understanding of diffusion flame structure and kinetics is afforded.
