Discrete-continual model of flame propagation in a gas suspension of metal particles. II. Allowance for the pre-flame oxidation reaction

Abstract

The previously developed discrete-continual mathematical model of propagation of combustion waves in air suspensions of reactive particles is supplemented by the preflame oxidation process. This allows us to describe some quantitative parameters of the flame in mixtures of air and magnesium particles.

Ignition and combustion of magnesium particles in a nonuniform thermal field

“…7); during this time, the first particle reaches the steady value of temperature T ≈ T m . Thus, the relay mechanism of ignition, which was previously observed within the framework of the pointwise approach [6,7], is also realized here.…”
