摘要
采用FDS模型模拟了大空间内发生火灾的烟气运动过程,分析了不同排烟模式下烟气控制的效果。模拟结果表明,补气口面积、火源功率对排烟效果影响较大;而排烟口的布置方式和排烟速率的影响较小。
Based on FDS model of Simulation smoke movement in large space, this paper analyses smoke control effect in different smoke exhaust patterns. The results show that making up air inlet and heat release rate have more influence on exhaust effect in contrast with the collocation of smoke vent and the velocity of smoke extraction.
