摘要
运用 FDS 模拟在特定机械排烟量下地下商场发生火灾时，观察不同细水雾喷头间距对火场烟气的控制影响。分析得到，在5 MW火灾功率下，排烟量60 m^3/（h·m^2）时，喷头间距2.0 m灭火效果较好，对大空间消防设计中喷头间距3.0 m更经济。
Using FDS simulation, under specific quantity of mechanical smoke exhaust, the effect of different spacing of water mist sprinkler on the fire smoke control was observed in case of a fire occurs in underground mall. From the analysis result, under the condition of fire power is 5 MW, smoke exhaust volume is 60 m^3/（h m^2）, nozzle spacing is 2.0 m, the extinguishing effect is best, the design of fire protection in large space with sprinkler spacing of 3.0 m is more economic.
