The modeling of fire and smoke spread is an evolving
field. As knowledge is acquired and resources become
available, models are enhanced to make their predictions
more accurate and/or their computations faster. This
paper will discuss the Consolidated Fire and Smoke
Transport (CFAST) zone fire model, developed by the
National Institute of Standards and Technology (NIST),
and a recent addition to that model, referred to as the
Corridor Flow Submodel. The goal of this new submodel is
to more accurately predict the flow of smoke down a
corridor which has an impact on fire protection issues
such as detection and escape time. Prior to the addition
of this new submodel, CFAST assumed that smoke traveled
instantly from one side of a compartment to another.
Development of the submodel will be discussed and then
the enhanced CFAST, Version 4.0.1 (executable dated
3/8/00), will be used to model a real-scale experiment
conducted onboard the ex-USS SHADWELL, the Navy's R&D
Damage Control platform.
