In cooperation with the fire protection engineering
community, a numerical fire model, Fire Dynamics
Simulator (FDS), is being developed at NIST to study
fire behavior and to evaluate the performance of fire
protection systems in buildings. Version 1 of FDS was
publicly released in
February 2000, and Version 2 in December 2001. To date,
about half of the applications of the model have been
for design of smoke handling systems and
sprinkler/detector activation studies. The other half
consist of residential and industrial fire
reconstructions. Throughout its early development, FDS
had been aimed primarily at the first set of
applications, but following the initial release it
became clear that some improvements to the fundamental
algorithms were needed to address the second set of
applications. The two most obvious needs were for better
combustion and radiation models to handle large,
spreading fires in relatively small spaces like
residences as opposed to industrial settings.
