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 flame speeds predicted by the detailed mechanism agree well with experimental results over the whole burning range,while those predicted by the one-step mechanism agree with experimental results only for fuel-lean conditions with quantitative and qualitative results bei.
详细机理预报的火焰速度在整个可燃范围都与实验结果吻合,而单步机理只在贫燃条件下才能给出定量相符的结果,在富燃条件下定性和定量预报结果均不合理。
