Abstract:
The second and most recent application of the NIST
Industrial Fire Simulation (IFS) System is to predict
the performance of sprinklers, draft curtains and roof
vents in storage facilities and retail spaces. The IFS
System is a series of computational fluid dynamics (CFD)
fire models based on large eddy simulation (LES)
techniques combined with means to exchange data and
results. The model requires as input information about
the activation properties of sprinklers and roof vents,
the spray distribution of the sprinklers, and the
burning and extinguishment properties of the commodity
under consideration. These are obtained from bench scale
and large scale experiments. The IFS2 model was
developed and evaluated using a series of heptane spray
fires and high rack storage fires of cartoned rigid
polystyrene cups.
