A Numerical Study of the Fire-Extinguishing Performance of Ultrafine Water Mist in Small Scale Tunnel Space

Abstract:

CFD simulation study on the fire-extinguishing performance of ultra-fine water mist (UFM) and its flow behavior in a small scale tunnel. Numerical simulation using dense gas model were carried outIt is discorvered that simulation shows that the larger size of fire is more difficult to extinguish in tunhenel space; and that the effect of obstruction in extinguishing efficiency depends on the location of obstruction.
