- Abstract
- The following pages present the results of a computer simulation analysis to establish a reasonable experimental design for post-flashover fire suppression tests to be completed by the Center For Fire Research at the U.S. National Institute of Standards and Technology (CFR-NIST). The computer simulation used in the analysis - called The Fire Demand (FD] Model - simulates the suppression of post-flashover charring and non-charring solid fuel fires in compartments using water sprays from portable hose-nozzle equipment used by fire departments. The output of this FD Model shows the extinguishing effects of hose-nozzle systems emitting water spray at various flow rates and droplet sizes. The calculations are baaed on a heat and mass balance accounting for gas and surface cooling, steam-induced smothering, direct extinguishment of the fuel and water spray induced air inflow and venting of heat and products of combustion. A discussion of the physical basis and computer details of the FD Model are presented in Reference 1 and results from the model in Reference 2, 3 and 4.
