Abstract

A theory for the thermal ignition of a fuel droplet in a hot oxidizing atmosphere is formulated using an existing gas-phase ignition criterion and an analysis for the transient droplet heating process. Limits on the ignitability of a system, either spontaneous or delayed, are identified. A kinetically controlled ignition regime and a droplet-heating-controlled ignition regime are shown to exist in cold and hot environments respectively, each exhibiting distinctively different ignition characteristics. Theoretical results yield reasonable agreement with existing experimental data.
