Abstract:
Fuel-rich laminar flat hydrogen-methane-air flames are studied numerically using the tracer method. It is found that, in the near-limit mixture, hydrogen has an advantage in the oxidation by oxygen. As the stoichiometric compositions are approached, this advantage decreases and then disappears. It is shown that Н$^*_2$О and СО$^*_2$ labeled additives participate in the reactions and the labels from these molecules move to other products. Small additives of CH$^*_4$ in the mixture completely react to form НН*О, Н$^*_2$О, СО, СО$_2$, НН*, and Н$^*_2$. Quantitative data on the distribution of the tracer atoms in products are given. The interaction of the hydrogen and methane oxidation schemes is studied. It is shown that in the presence of restriction on the interaction of these schemes, the laminar flame velocity increases by a factor of 5–7.
Keywords:
