Physicomathematical modeling of ignition and combustion of silane in transient and reflected shock waves

Physical and mathematical modeling of one-dimensional and two-dimensional structures of detonation waves in a silane-air mixture

“…1) as it was in [3]. At the same time, the reduced kinetics model provides monotonous distribution of flow parameters, which means that the heat release in the reaction zone is monotonous.…”

“…To describe the kinetics of ignition and combustion of this reacting mixture, we use the detailed kinetic scheme [1][2], which takes into account 140 forward and backward reactions of 25 species (H2, O2, H2O, OH, O, H, HO2, H2O2, SiH4, SiH3, SiH2, HSiO, SiH2O, SiH3O, SiH3O2, xSiH3O2, SiH3OH, SiH3O2H, SiH2OH, HSiOOH, SiOOH, SiO, SiO2, N2, Ar). Note that earlier [2][3][4][5], using this kinetic model, we have been able to describe: -ignition delay times of silane/hydrogen/air mixtures and give an analytical approximation dependence for its description; -the ignition limits of silane-oxygen and silane-air mixtures. In this paper, we will use this model and the reduced kinetics to calculate the DW structure in silane-air mixture.…”

“…Earlier we used the detailed kinetics models to calculate: -the DW propagation, attenuation and suppression in reactive gas mixtures with inert particles [6][7][8][9]; -geometrical limits of detonation [10][11]; -ignition delay times of reactive gas mixtures [3,6] and others. In these papers a lot of advantages of detailed kinetics models were presented.…”

The ignition delay times of hydrogen/silan/air mixtures at low temperatures

“…Note that earlier [2][3][4][5], using this kinetic model, we have been able to describe: -ignition delay times of silane/hydrogen/air mixtures and give an analytical approximation dependence for its description; -the ignition limits of silane-oxygen and silane-air mixtures.…”

“…Several ignition criteria are used for determining the ignition delay times [3,6]. It was shown [3,[6][7] that the use of different ignition criteria yields very close results for both hydrogen-oxygen-argon mixtures and silanehydrogen-oxygen-nitrogen-argon mixtures.…”
