Краткое описание
Three-dimensional direct numerical simulation of a stoichiometric methane−air turbulent premixed planar flame propagating in homogeneous isotropic turbulence is conducted to investigate local flame structures in thin reaction zones. The detailed kinetic mechanism (GRI-Mech 3.0) which includes 53 reactive species and 325 elementary reactions is used to represent methane−air flame. For a better understanding of the local flame structure in thin reaction zones, distributions of mass fractions of major species, heat release rate and temperature are investigated. To clarify effects of turbulence on the local flame structures in thin reaction zones, the statistical characteristics of flame elements are revealed.
