| 摘 要： | 本文对水平管道中瓦爆炸传播火焰的厚度进行了实验研究，对不同浓度的瓦斯／空气爆炸火焰的厚度及传播速度进行了实际的测量，得到了火焰厚度变化的基本规律。在本实验条件下所测得的实际火焰厚度较厚， 而且变化范围较大，其厚度比按传统的静态火焰模型计算出的结果大得多。该实验结果为泊瓦斯爆炸机理的研究、瓦斯爆炸模型的建立以及数值模拟提供了可靠的实验数据。

| Abstract: | In this paper,the flame thickness and flame propagating speed in gas explosion at different concentration ratio of methane/air mixture have been determined experimently and the basic rule of variation of flame thickness is obtained. In the test, the measured flame thickness and the range of variation are both larger than that calculated by static flame model. The results obtained are of great advantage for further study of gas explosion mechanism, establishment of gas explosion model, and numerical simutation.[ |
