Sprinklers, Vent, and Draft Curtain Interaction: Modeling and Experiment



Kevin B. McGrattan, Anthony P. Hamins, D. D. Evans


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 polystyrene cups.
