| 中文摘要: |
| 建筑火灾中轰燃现象是一种典型的突变过程。本文利用数学方法推导出轰燃的突变动力学,首先给出基于能量平衡方程的轰燃模型并构建其突变簇方程,然后讨论系统控制因子和实际工况之间的关系。结果发现建筑火灾中轰燃现象的突变形式是燕尾突变。 |
| 英文摘要: |
| By physical observation, flashover in building fires is a suggestive of a catastrophe process. In this paper, catastrophe dynamics of flashover is investigated by mathematical method. Firstly, a model of flashover based on energy balance equation is established. Secondly, the corresponding relationship between system control variables and operating conditions is discussed. The results indicate that flashover in building fires is in essence a phenomenon of swallowtail catastrophe. |
