Abstract:
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. 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 residen-tial and
industrial fire reconstructions. Throughout its
development, FDS has been aimed primarily at the first
set of applications, but it is now clear that some
improvements to the fundamental algorithms are needed to
address the second set of applications. The two most
obvious needs are for better combustion and radiation
models to handle large fires in relatively small spaces,
like scenarios involving flashover.
