Modeling Horizontal Smoldering Spread in a Narrow Channel

Smoldering spread along a horizontally-oriented thin cellulosic solid in a narrow channel is a representative near-limit fire phenomenon. Because of the narrowness of the domain, the phenomenon allows reduced-dimensional modeling. This paper presents a one-dimensional model, which considers two reactions, i.e., cellulose pyrolysis that produces char (and gaseous species) and char oxidation. Traveling-wave solutions are numerically obtained by a...
