| 摘 要： | 分别用实验和数值计算的方法研究了脉冲切断时管道的阻力特性,指出总管和支管压力波动的差值随切断比的增加而减小,不同支管切断位置对压力波动的影响呈现中间大,两头小的现象,为工业炉的脉冲燃烧控制系统中控制燃烧器的流量稳定提供了理论依据。

| Abstract: | The resistance character of pipeline while pulse cut off was researched with both experiment and numerical methods.Research shows that the difference of pressure oscillation between header pipe and branch pipes decreased with an increase in the pulse cut-off ratio,and pressure oscillation is more sensitive while middle chance pipes cut off than while ends pipes cut off. |

| Keywords: | pulse combustion cut-off ratio resistance character |
