- Abstract
- Smoldering combustion is a self-sustained, propagating exothemic reaction wave deriving its principal heat from diret attack of oxygen on the surface of a fuel. Such processes are encountered in a variety of contexts, such as fire safety, industrial processing, resource recovery and, of course, cigarette smoking. There can be a tremendous degree of variation in the lenght and time scales, as well as in overall behavior, among these manifestations of what are fundamentally similar underlying phenomena. A few examples from different areas are examined here to illustrate this. The generalized elements of a comprehensive model of smoldering propagation are briefly examined; it will be apparent that such a model is intractable and must be pared down to approximately describe specific application. Several such specific models from the literature are surveyed here.
