✦ Synopsis

Peters and Smooke [1] recently proposed a four-step model to explain the phenomenon of the lean flammability limit. Close examination of the model reveals, however, that the phenomenon is not exactly the lean flammability limit as customarily perceived (by Coward and Jones [2], for example). In fact, the phenomenon revealed, which we call kinetic extinction, can be modeled by a simpler three-step model, the two-step Zeldovich-Lifidn model [3] augmented by an additional reaction. In the context of this model, we analyze the mechanism of kinetic extinction which manifests itself in the establishment of a critical flame temperature below which a mixture cannot burn.
