摘要
在试验的基础上,研究了瓦斯爆炸过程中壁面粗糙度对火焰传播速度和超压的影响。研究结果表明:壁面粗糙度对瓦斯爆炸过程影响非常明显,粗糙管道的火焰速度和超压均比光滑管道有大幅提高,得出了不同粗糙度时火焰速度峰值和压力波超压峰值的变化规律。
On the basis of experiment, the influence of wall roughness on fire transmission and overpressure in gas explosion was investigated. The research result shows that the influence of wall roughness in gas explosion is obviously, the flame propagation speed and the overpressure in rough conduit is much higher than that in plain tube; the change rule of the flame propagation speed peak value and the overpressure peak value with increasing roughness was obtained.
