摘要
为得到爆震管内同一截面上压力波的分布特性,在60 mm×60 mm×2000 mm方爆震管内,用乙炔(C2H2)和空气混合物进行了单爆震研究.在距离封闭端1400,1600 mm两个截面的不同位置处分别安装4个高频响压力传感器测得压力值.实验在光滑爆震管和安装扰流器的爆震管内分别进行,结果表明:①同一截面的压力波大小并不一样,安装扰流器的爆震管内得到充分发展的爆震波,且爆震波不是一个平面波;②壁面处压力波的压力大于爆震管道中间压力.
In order to gain the distribution characteristic of pressure in same section of detonation tube, a series of single detonation experiments were conducted to study acetyleneair mixtures in square detonation tube. Four pressure transducers were installed respectively in different positions of two sections to measure the pressure value. The experiment was performed respectively in tube with/without obstacles. The results indicate that the size of pressure wave in same section is different and the detonation wave is not a plane wave. The pressure in tube wall is higher than that in tube center.
