Abstract

The detailed interaction of a premixed methane-air flame with a two-dimensional counter-rotating vortex pair was studied using mixture-averaged transport properties for stoichiometric and rich N₂-diluted reactants. The significance of using the more accurate transport model depended on the particular aspect of transient flame response under consideration. While the effect on global response was generally small, quantitative differences of ≤ 30-45% in the extend of transient accumulation of some species on the reactants side of the flame. No significant qualitative differences were observed in the transient flame response. Original is an abstract.
