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.
