叙述了瓦斯爆炸过程中火焰与超压的实验研究情况 ,介绍了瓦斯爆炸过程中火焰与超压之间的关系。研究结果表明 :在瓦斯爆炸过程中 ,火焰速度传播规律可表示为 :V =m× (L/D) +b;随着障碍物的增多 ,火焰传播规律的线性度降低 ,非线性度增大 ,瓦斯爆炸过程中的冲击波阵面的强度与火焰的速度有关。 The experimental research on flame and overpressure in gas explosion process is described. The relationship between flame and overpressure in gas explosion process is introduced. The results show that the propagation law of flame velocity can be expressed as V = m × (L / D) + b in the process of gas explosion. With the increase of obstacles, the linearity of flame propagation decreases and the nonlinearity increases The intensity of the shock wave front during the gas explosion depends on the speed of the flame.
