Аннотация

The influence of the choice of a detailed kinetic mechanism (DKM) on the structure of a laminar flame for lean hydrogen-air mixtures has been studied by means of numerical simulation using a CHEMKIN-Pro software module. It is shown that the choice of three detailed kinetic mechanisms (DKMs), differing in the rate constants of elementary reactions, the number of reaction pathways, and the presence of additional components, has virtually no effect on flame propagation velocity and flame structure. It is found that small differences in the local sensitivity of heat release to elementary reactions can provide reliable information on possible ways of influencing flame propagation.
