摘要:
为了研究矿井瓦斯爆炸火焰发展过程中结构与参数的动态变化特征,建立小尺寸管道气体爆炸实验平台,结合高速纹影摄影技术,探测了不同浓度的甲烷-空气预混气体火焰在管道内传播的结构变化特性,并得出速度变化特征曲线。同时建立相应的数学模型和物理模型,通过模拟实验研究管道内气体爆炸反应过程中火焰传播速度变化过程,计算图像和实验图像走向趋向一致。
Abstract:
The experimental system was built up to detect the flame propagation in pipes,which was consisted of small-sized pipe and the high-speed video,then the changes of velocity characteristic curve were obtained.Meanwhile the corresponding mathematical model and physical model were established,through which the the speed variation during the flame propagation was obtained.The calculated results were in good agreement with experimental results.
