| 摘 要： | 采用射流火焰的点火方式进行了爆震管中乙炔和空气混合物从爆燃向爆震转捩的实验研究.爆震管一端开口一端封闭,在封闭端与爆震管垂直安装预燃室,采用火花塞在预燃室中点火,形成射流火焰引燃爆震管中的混合物.基于光电转换原理研制的火焰测速系统测量了爆震管中火焰传播速度.实验表明,与在爆震管壁面火花塞点火相比,射流火焰点火加大了爆震...

| Abstract: | A detonative tube filled with acetylene and air by flame jet ignition was designed to study deflagration to detonation transition.The detonative tube was one end opened and the other end closed.A pre-combustion chamber was installed at the closed end perpendicularly to detonative tube.Flame jet produced by spark plug ignition in pre-combustion ignited the mixture in detonative tube.Flame propagation velocity in duct was measured by a system based on photoelectric transition principle.Compared with spark plu... |
