摘要：
In the present study, the effect of random distribution of reactants and products on laminar, 2D and steady-state flame propagation in aluminum particles has been investigated. The flame structure is assumed to consist of a preheat zone, a reaction zone and a post flame zone. It is presumed that in the preheat zone particles are heated and reaction does not exist. Energy conservation equations of laminar flame had been solved two-dimensionally for different zones and algebraic equations of flame speed are obtained. Finally, gas temperature distribution in different flame zones in the channel and also flame speed changes in terms of particles diameter, equivalence ratio, and channel width in random media are compared with previous experimental and theoretical results. The results show a reasonable compatibility with this theory and experimental data.
