Abstract:

Asymptotic techniques based on the limit of high activation energy have been used to analyze the ignition process of a condensed fuel suddenly exposed to a hot stagnant gas. Several cases are studied differing in the location of the exothermic ignition reaction. In a first part, an analysis is presented of the gasification process when an equilibrium process or a rate process is considered to determine the gasification rate, and the use of these results to study ignition by a fast exothermic gas-phase reaction. In a second part an analysis is presented of ignition by a heterogeneous exothermic reaction including the convective effects of the gasification flow. In a third part an analysis is presented of ignition by a condensed phase reaction and the derivation of a closed form expression for the ignition time. In a fourth part an analysis is presented of the heterogeneous ignition process by convective heating described by a Newtonian law. Details of these analyses are given in previous Scientific Reports.
