| 摘 要： | 采用传动的热力理论，在火焰上建立热能平衡式，该平衡式不仅考虑了新鲜混合气的热焓变化以及反应过来的热量，更进一步了考虑燃烧反应本身的放热率，采用奇异摄动法得到预混丁烷气的流火焰传播速度表达式，并与采用本生灯试验测试系统测得的预混气平均火焰传播速度进行了比较，得到了较为满意的结果。

| Abstract: | Based on thermal theory a mathematical model concerning the problem is established from the aspect of energy balance.As a result of forceful non linear of reaction speed,the method of singular perturbation is used to get an accurate solution.A set of Bunsen burner device is used to measure average flame propagation speed.Compared with the experimental data,the calculation results show that the model is satisfactory. |
