THERMAL STABILITY OF A REACTIVE SPHERICAL SHELL

Abstract

The conditions required for the spontaneous ignition of a volatile fuel drop suddenly exposed to a hot oxidizing environment have been investigated theoretically using a simplified model of the physical situation. Analysis of the model, a reactive spherical shell with unequal boundary temperatures, defined the conditions consistent with thermal stability of the shell. Two types of reaction rate were used, one with a simple Arrhenius form, and a second explicitly involving radial distance as well as a temperature dependence in Arrhenius form.
