Abstract:

Urban/wildland intermix conflagrations occur when dry vegetative fuels of the wild areas combine with structural fuels from houses to product a combustible environment that, once ignited, easily becomes uncontrollable. The dominant mechanism for propagation of these fires is the copious fire brands these fuels produce. This research is a first step in the development of a modular model for fire growth in the urban/wildland intermix. The goal is to predict the area that is at risk from brand-induced fire spread during a large conflagration. Our work expands that performed by Tarifa, et al., substituting a more realistic plume velocity field based on the Baum and McCaffrey plume model for the constant plume velocity assumed there.
