Abstract

Eight combustion models for burning brands are reviewed. An averaged stagnation-point burning model, using the chemical properties of wood, is used here. Maximum propagation distances are calculated for disk-shaped brands lofted in large fires, such as occur after earthquakes or at urban/wildland interfaces. Lofting in the fire plume and propagation downwind are approximated here with distinct flow fields: a Baum and McCaffrey model for the plume and a constant horizontal velocity driving downwind propagation. In the plume, the brands rise with maximum drag and no lift. During propagation, both lift and drag act on the brand. It is assumed to have a fixed angle of attack, 35 deg
