Intumescent chemical systems are designed to swell into
a thick, robust foam upon exposure to heat, protecting
the underlying material from fire by providing a
physical barrier to heat and mass transfer. The
mechanisms determining the fire-resistant properties of
these materials are not well understood. Various
approaches to modeling intumescent behavior are
reviewed. A three-dimensional model that incorporates
physical and chemical phenomena at the scale of a single
bubble is described.
