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 HO2 radicals, and the quadratic branching reaction H + HO2 → OH + OH. The second maximum in the OH concentration profile is due to the classical high-temperature branching reactions H + O2 → OH + O and O + H2 → OH + H. __________ Translated from Fizika Goreniya i Vzryva, Vol. 43, No. 2, pp. 3–9, March–April, 2007. |
