Abstract:
On the basis of the latest experimental data using a detailed kinetic model, the influence of kinetic features of ultrarich methane-air mixtures (in comparison with ultralean ones) on the main characteristics of superadiabatic waves of filtration combustion of gases is considered. It is shown that substantially lower concentrations of O, OH, and H radicals are typical of ultrarich mixtures, which results from effective inhibition of atomic hydrogen participating in the chain branching reaction H + O22 = OH + O by methane in the reaction H + CH44 = CH33 + H22. Therefore, extension of the preheating zone and noticeable expansion of the heat-release region are typical of rich compositions. A decrease in generation of the main radicals in ultrarich mixtures (as compared to ultralean compositions) leads to an increase in the maximum skeleton temperature by ≈≈300–350 K and to a significant increase in velocity of wave-front propagation.
