Abstract:
A combination of numerical modeling and large scale
experimentation has yielded a tremendous amount of
information about the structure, trajectory and
composition of smoke plumes from large crude oil fires.
A numerical model, ALOFT (A Large Outdoor Fire plume
Trajectory), has been developed at NIST to predict the
downwind concentration of smoke and other combustion
products. The model is based on the fundamental
conservation equations that govern the introduction of
hot gases and particulate matter from a large fire into
the atmosphere. The model has been used to estimate
distances from fires under of variety of meteorological
and topographic conditions where ground level
concentrations of smoke and combustion products fall
below regulatory threshold levels.
