| 中文摘要: |
| 研制一种重现火灾轰燃的化学燃料和氧化剂的混合燃料,通过调整燃料的配方,可实现模拟控制火灾轰燃的温度和烟气产生量;实验研究了火灾轰燃过程烟气参数的变化规律,说明建筑火灾烟气运动的场-区-网模拟模型是合理的,分析了火灾过程中烟气的产生、运动、回流、下沉现象物理机制,指出在受限空间火灾救灾过程中应注意的问题。 |
| 英文摘要: |
| A fuel mixture of chemistry fuel with oxidizing agent has been developed for re-appearing a fire flashover of confined compartment. The flashover temperature and smoke production could be controlled by adjusting the dispensation of fuel mixture. The Field Zone network model proved to be feasible by analyzing the variable regularity of smoke parameters of fire flashover, and the physical mechanism of smoke production and movement and back flow and fall-in during the process of fire flashover is analyzed. The key problems in the process of fire fighting are also mentioned. |
