Abstract
Numerical simulations are used to study the effect of the chemical composition of the combustible mixture on the development of the hydrodynamic instability of the flame front, its acceleration, and the possibility of transition to the detonation regime. The combustion of hydrogen-containing mixtures in confined spaces (channels) was considered. Calculations were performed within the framework of a two-dimensional hydrodynamic model for the combustion of premixed mixtures with account of viscosity, heat conduction, multicomponent diffusion, and chemical kinetics. It was demonstrated that the presence of an inert component and the deviation of the mixture composition from stoichiometry caused not only a quantitative but also a qualitative change in the character of burning of gaseous combustible mixtures.
