Abstract:
A numerical modeling study of the propagation of a laminar flat homogeneous gas flame has shown that in a hydrogen-air flame, a rapid increase in the concentration of OH radicals begins in the range of low temperatures and the concentration profile has two maxima. The first maximum in the low-temperature region of the front is related to the diffusion of H atoms, formation of HO$_2$ radicals, and the quadratic branching reaction H + HO$_2$ $\to$ OH + OH. The second maximum in the OH concentration profile is due to the classical high-temperature branching reactions
H + O$_2$ $\to$ OH + O and O + H$_2$ $\to$ OH + H.
Keywords:
chain avalanche, flame propagation, diffusion, hydrogen atoms, quadratic branching.
