| 摘 要： | 在实验的基础上,研究了电磁场对瓦斯爆炸过程中火焰传播和爆炸波的影响.研究结果表明：电磁场对瓦斯爆炸过程影响非常明显，加电磁场后瓦斯爆炸火焰传播速度和爆炸波超压均比光滑管道有大幅提高，而且随着电磁场强度的增加，影响程度加强.基于电磁场对瓦斯爆炸传播特性的实验结论，从理论上分析了电磁场对瓦斯爆炸的影响机理，并对实验现象做出了合理的解释.但是由于电场与磁场在瓦斯爆炸过程中的互相制约，电磁场效应不是磁场效应和电场效应简单的相互加剧关系.

| Abstract: | On the basis of the experimental research,the influence of electromagnetism field on flame transmission and explosion wave overpressure in gas explosion was investigated.The research results show that the influence of electromagnetism field in gas explosion is obvious,the flame propagation speed and explosion wave overpressure in electromagnetism field is much higher than that in plain tube,and the more stronger the intension of electromagnetism is,the more greater the influence.Based on the experimental results,the influence mechanism of electromagnetism field on gas explosion propagation character was analyzed and had an reasonable explain.As the restrict affection of the electric field and the magnetic field in gas explosion,the influence of electromagnetism field unequal to the sum of the electric field and the magnetic field. |
