Modeling of smoldering combustion propagation
TL;DR: In this article, the authors focus on the coupled chemical and physical processes involved in self-sustained propagation of smoldering and conclude that even for the most-studied case of cellulose, the chemical mechanisms involved in these processes are both too complex and too poorly understood to be included in a smolder propagation model.
