Authors Abstract
Content
Three-dimensional direct numerical simulations of methane-air turbulent premixed flame propagating in homogenous isotropic turbulence are conducted to investigate local and global flame structure in thin reaction zones. GRI-Mech 3.0 is used to represent methane-air reactions. The equivalence ratio of unburned mixture is 0.6 and 1.0. 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 and global flame structures, the statistical characteristics of flame elements are also revealed.
