Abstract
A one-dimensional integral model is formulated to describe the transient burning of charring materials. In the model, the sequence of events occurring in a material when exposed to a fire environment is divided into following sequential phases: (I) initial heating phase, (II) pyrolysis phase, (III) char oxidation phase. The calculated mass loss rates are shown to be in reasonable agreement with the existing experimental data. The burning model is then incorporated into a one-layer zone compartment fire model. The fuel inside the compartment is divided into multiple fuel elements, and the compartment fire behaviors are described as the consequence of the burning of each of these fuel elements. The comparison with experimental data in the literature also agreed well.
