A computational fluid dynamics (CFD) model of fire and
smoke transport is described. Combustion is represented
by means of a single conserved scalar known as the
mixture fraction. Radiation transport is approximated in
the gray gas limit. The algorithms have been
incorporated in the Fire Dynamics Simulator (FDS), a
computer program maintained by the National Institute of
Standards and Technology. Sample calculations are
presented demonstrating the performance of the new
algorithms, especially as compared to earlier versions
of the model.
