摘要
采用FDS模拟某仓库火灾,并与实验结果比较温度曲线和火灾蔓延过程。在仓库中放置三层金属货架,分打火机和烟头两种引燃方式和不同点火位置进行实验。模拟与实验得到的温度曲线相似度很高。250s前模拟与实验得到的火灾蔓延过程比较相似,250s后由于纸箱倒塌,模拟结果出现延迟。合理摆放货物的情况下烟头引燃仓库火灾的可能性较小。
The temperature curve and fire spread of a fire in store- house were simulated by FDS and were compared with experiment results. The fire experiments ignited by cigarette or lighter in different location were done on a 3-layer mental shelf in storehouse. The temperature curves achieved by simulation or experiment were very similar. The spread of fire achieved by simulation or experiment were similar before 250 s. The collapse of paper box after 250 s made the fire spread in simulation a little later than in experiment. The cigarette could hardly ignite the whole storehouse if the goods been set rightly.
