โœฆ Synopsis


A numerical model including a detailed chemical kinetic reaction mechanism is used to study laminar flame propagation in ethylene--air and ethylene-oxygen mixtures. The effects of variations in pressure, equivalence ratio, unburned mixture temperature, and oxidizer on computed flame properties are examined. The results of the addition of various halogenated flame inhibitors to ethylene-oxidizer mixtures are estimated. In each case the kinetic factors responsible for the observed behavior are identified.
