Combustion waves in a model with chain branching reaction and their stability
In this paper the travelling wave solutions in the adiabatic model with two-step chain branching reaction mechanism are investigated both numerically and analytically in the limit of equal diffusivity of reactant, radicals and heat. The properties of these solutions and their stability are investigated in detail. The behaviour of combustion waves are demonstrated to have similarities with the p...
متن کاملPulsating Instabilities of Combustion Waves in a Chain-Branching Reaction Model
In this paper we investigate the properties and linear stability of travelling premixed combustion waves and the formation of pulsating combustion waves in a model with two-step chain-branching reaction mechanism. These calculations are undertaken in the adiabatic limit, in one spatial dimension and for the case of arbitrary Lewis numbers for fuel and radicals. It is shown that the Lewis number...
متن کاملPulsating Behaviour in Combustion Waves
ames. The models differ in their kinetic mechanisms, i.e. one-step and two-step chainbranching reaction schemes are considered here. It is shown that in these models there exists a variety of dynamical regimes of nonlinear wave propagation depending on the control parameters. These regimes include travelling waves, pulsating periodic waves, pulsating waves emerging due to the period-doubling bi...
متن کاملCombustion Behind Shock Waves
Laminar hydrocarbon flames, which have adiabatic flame speeds on the order of a meter per second, are conventionally described by a leading convective-diffusive zone followed by an energyreleasing reactive-diffusive region. On the other hand, combustion induced by a strong shock wave is typically modeled as a convective-reactive balance with negligible diffusion, which may be called a convectiv...
متن کاملAb initio study of chain branching reactions involving second generation products in hydrocarbon combustion mechanisms.
sec-Alkyl radicals are key reactive intermediates in the hydrocarbon combustion and atmospheric decomposition mechanisms that are formed by the abstraction of hydrogen from an alkane, or as a second generation product of n-alkyl H-migrations, C-C bond scissions in branched alkyl radicals, or the bimolecular reaction between olefins and n-alkyl radicals. Since alkanes and branched alkanes, which...
