Simulation on dynamic pressure of premixed methane/air explosion in open-end pipes

  • 摘要: 为了研究瓦斯爆炸冲击波的动压演化规律,利用数值模拟软件模拟开口型管道内的爆炸。结果表明:动压与流速在时间上存在较好的对应关系,基本同时出现正向和反向的峰值;动压在3个方向上不仅伴随传播距离的增大而不断增大,也伴随传播时间的延长而增大;沿管道方向(火焰传播方向)上的最大动压值是其他2个方向(管道径向)上的数千倍;相比爆炸超压而言,管道径向上的动压对爆炸破坏效应的影响较小,而沿管道方向上的动压造成的破坏效应不能忽视;验证了动压与流速的平方呈正比关系,同时通过分析给出了动压基于管道几何尺寸和流速的经验公式。
