摘要
全氟己酮灭火系统管网的流动特性对于灭火剂喷射时间和状态具有重要影响,进而影响整个系统的灭火效能。本文利用基本工程流体力学模型对全氟己酮灭火系统灭火试验的管网流动进行理论计算,定性分析了管网流动过程的不同阶段,定量研究了各阶段管网压力、流量及灭火剂喷放时间等重要特征参数。研究揭示了全氟己酮灭火系统管网内的流动特性,为进一步开展系统管网工程设计计算提供了理论依据。
The flow characteristics of the pipe network of the perfluorophenone fire extinguishing system have an important influence on the time and state of the fire extinguishing agent injection,which in turn affects the fire extinguishing efficiency of the whole system.In this paper,a fluid mechanics model has been adopted to calculate the pipe flow of the perfluorohexanone fire extinguishing system.Different stages of the pipe flow process have been analyzed qualitatively,and the important characteristic parameters such as pipe pressure,flow rate and agent discharge time in each stage have been studied quantitatively.The study revealed the pipe flow characteristics of the perfluorohexanone fire extinguishing system,providing a theoretical basis for further engineering design and calculation of the system pipe network.
