摘要
该文以易燃物质运输中的火灾事故为研究对象,建立相间耦合的Eulerian-Lagrangian模型和颗粒随机轨道模型。利用组分混合分数模型,对隧道内装载液化丙烷的车辆发生泄漏引起的火灾事故进行数值研究。计算结果给出了隧道内发生非预混燃烧时流场的温度分布及其变化情况。结合安全系统工程理论对隧道内火灾事故进行分析,利用"人-机-环"理论提出相应的预防策略,为科学预防火灾事故的发生以及指导紧急救灾提供理论依据。
For the fire accident in the flammable materials transportation, two-phase-coupled Eulerian-Lagrangian model and particle stochastic model are established, and a numerical simulation of fire accident of leakage of the truck filled with liquefied propane in tunnel is conducted based on the component mixture fraction model. The computed results give the distribution of flow temperature in tunnel. According to the theory of Safety System Engineering, fire caused by two-phase dispersion of pro- pane release in the tunnel is studied, and the prevention measures are presented combining humanmachine-environment theory, which gives theoritical basis of predicting fire accident and directing urgency succor.
