摘　　要：为实现简单空间内部火场温度的变化过程的快速预测,首先对火灾双层区域模拟方法进行了改进,并利用该方法对船舶机舱火灾类空间火灾进行了模拟研究;然后,将模拟结果与成熟的火灾场模拟软件FDS的仿真结果进行了对比研究。结果表明:改进后的区域模拟方法实现了上下区域的温度都随时间增加不断增加的效果;在火灾初期,区域模拟结果与FDS仿真结果吻合较好,且该计算方法耗时非常少,大大弥补了FDS计算量大、耗时长的缺陷;在火灾后期区域模拟结果与FDS仿真结果差值较大。To predict the temperature development process of simple fired cabin,the primary zones-simulation method is improved,and the improved method is used in the study of a cabin fire.Then the fire simulation software FDS is used in the same cabin to validate the new method.By contrasting the results of the two models,it is found that the temperature in the up and down zones increases with time,the datum gained from the new method tallies with that of FDS at forepart,and the new one takes a little time.
