摘要: Abstract : The interaction of a premixed methane/air flame with counter-rotating vortex pair is analyzed using parallel low-Mach-number computational model that based on detailed C1C2 chemical mechanism. Attention focused the transient response heat release rate and structure at centerline pair. Results are obtained for pairs different strengths under lean, stoichiometric, rich conditions. For range considered, computations indicate in decays significantly faster than stoichiometric flame; this behavior consistent recent experimental measurements. Meanwhile, lean slightly slower flame. radicals such as H, CH, OH, HCO also analyzed. analysis reveals complex nonlinear dependence both strength stoichiometry.
