摘要:
为了有效抑制气体爆炸时产生的冲击波强度,设计加工了内部截面为110 mm×80 mm,长500 mm的爆炸实验管道,利用高频动态压力传感器,对比研究了泡沫镍在管道内的安放位置对甲烷-空气预混气体爆炸的影响。结果表明:当把泡沫镍铺设在管道中间位置时其对爆炸超压的抑制效果最好,其次是放置在管道的尾部,效果最差的是将多孔材料放置在管道的前部。
Abstract:
In order to suppress the shock wave intensity of gas explosion effectively, an explosion experimental duct with the internal cross-section of 110 mm × 80 mm and the length of 500mm was designed, and the high frequency dynamic pressure sensors were used to comparatively study the influence of laying positions of nickel foam in the duct on the explosion of methane-air premixed gas. The results showed that the suppression effect on the explosion overpressure was the best when the nickel foam was located at the middle part of the duct, and followed by the end part, while the effect was the worst when the porous material was located at the front part of the duct.
