Abstract

Computational Fluid Dynamic (CFD) models are used to investigate the suppression of liquid-fuel pool fires using fine watersprays in an effort to understand the extinguishment mechanisms involved. The model calculates fuel evaporation and its subsequent combustion, as well as the injection and flow of the fine water droplets and the interaction between the water droplets and the hot gases. The model was used to simulate full-scale experiments carried out at the National Fire Laboratory using a mobile test facility that simulates liquid-fuel pool fires in an open space. Comparisons were made of the fire plume temperatures before the activation of the nozzles and the water flux density at floor level without the fire. Four simulations were conducted. In one, the fine waterspray
