A method of studying the large scale transport of smoke
and hot gases induced by fires in enclosures is
described. The approach is based on solving the
governing equations directly (if approximately) by
decomposing the fire-driven flow field into large scale
convective and small scale combustion components. In
this work, results involving large scale convective
transport generated by flow fields associated with
typical fire scenarios are presented. The large scale
flow is studied using finite difference techniques to
solve large eddy simulations of the Navier-Stokes
equations at high Reynolds numbers. No empirical
turbulence models are employed. The basic theory behind
the methodology is outlined and sample results of both
large and small scale phenomena are presented and
compared with related experiments.
