| 摘 要： | 为得到爆震管内同一截面上压力波的分布特性,在60mm×60mm×2000mm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1400,1600mm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.

| Abstract: | 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 acetylene-air 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. |
