摘　　要：细水雾灭火以其高效、环保的特点,已成为最具潜力的哈龙灭火系统替代技术之一。本文采用计算流体力学(CFD)的方法,使用火灾场模拟软件FDS4.05模拟研究细水雾灭火系统对空间4个位置油池火的灭火效果。研究结果表明,细水雾对喷头正下方的火源灭火效果最好,且灭火效果随火源距离喷头横向距离的增加而减弱。Water mist has beco replacements of Halon with environment compatibility. The Simulator FDS4.05 available in study the extinguish pool fire landscape orientation distance o efficiency of extin when the fire under the me one of the most potential high efficiency and friendly fire field model Fire Dynamics the literature will be applied to by water mist with 4 kinds f the nozzle to fire. The result guish fire by water mist is the best nozzle, And the efficiency is lower when the landscape orientation distance is longer.
