On Traveling Front of Ignition in Co-Flow Laminar Reactive Jets

Abstract

In this paper we derive a simple, still experimentally feasible, model for propagation of traveling fronts of ignition which were recently observed in experimental studies of autoignition of co-flow reactive jets at high pressure. We obtain a closed form analytical solution for this model and present a detailed analysis of this solution. We also present a qualitative comparison of the model predictions with available experimental data.
