Abstract
The equations of one-dimensional laminar flame propagation were numerically resolved to study the formation of NO2 in the premixed methane-air and hydrogen-air flames at atmospheric pressure. The results show the formation of NO2 peak in the flame region prior to the rapid formation of NO (say prompt NO) in the methane flame, whereas they do not show the formation of NO2 peak in the hydrogen flame in which NO is not formed rapidly. The formation of NO2 in the flame is controlled by the concentration and formation rate of prompt NO as well as the concentrations of HO2 and H, mainly through the reaction of NO + HO2→NO2 + H.NO2 is consumed mainly through the reaction of NO2 + H→NO +OH coincidently with the rapid appearance of NO.Keywords
