摘要
由于船舶自身空间狭小,通气性能差,且舱体内部存在燃油等大量易燃物品,因此当船舶发生火灾时会造成巨大危害。传统的针对地面封闭建筑的火灾模型无法正确预测火灾的蔓延速度和熄灭时间,因此需要对船舶封闭空间建立火灾模型。本文使用实验舱体建立实验系统,并确定火源及质量损失速率、温度、气体组分等测量方法。通过对参数的分析,建立了火灾状态模型,并可以精确预测火灾的熄灭时间。
Due to the fact that the ship's space is narrow and the ventilation is poor, and the cabin is equipped with massive combustibles, the fire would do great damage to ship. The traditional model cannot predict the rate of speed and extinction time, hence it is necessary to build a model for cabin enclosed space. This paper builds an experimental system with experiment cabin and determine the measurements of fire and quality loss rate, temperature and gas component. Through analysis on parameters, this paper builds a model of fire state and predicts the extinction time accurately.
