爆轰火焰在管道阻火器内的传播与淬熄特性OA北大核心CSCDCSTPCD
Detonation flame propagation and quenching characteristics in crimped-ribbon flame arrester
在水平封闭的直管中,采用自主研制的阻爆实验系统(包括传感器系统、配气系统、数据采集系统、点火系统等)对不同活性预混气体爆轰火焰在波纹管道阻火器内的传播与淬熄过程进行了实验研究.结果显示当可燃气体接近当量浓度时(丙烷4.2%、乙烯6.6%、氢气28.5%,均为体积分数),预混气体从点燃到火焰淬熄过程历时非常短,总体可分为4个阶段,缓慢燃烧阶段、快速燃烧阶段、加速燃烧阶段和超压振荡阶段.丙烷-空气、乙烯-空气预混气体在D=80 mm的管道阻火器中,爆…查看全部>>
A self-designed explosion suppression experimental system including sensor detection system, gas mixing equipment, data acquisition device and electric spark ignition device was set up to investigate various fuel/air premix detonation flame propagation and quenching by crimped-ribbon flame arresters in horizontal pipe that closed at both ends. Detonation experiment showed that when the concentration of flammable gas was close to the stoichiometric ratio, (4.…查看全部>>
