| 摘 要： | 介绍了用USED CARS技术测量对撞式甲烷/空气扩散火焰前滞止区和尾流区的温度分布剖面。在滞止区富甲烷边观察到甲烷燃烧前的热解过程;尾流区温度高于滞止区温度,表明在滞止区有未完全燃烧的中间产物存在,在尾流区发现C2及CH的光谱也证明了这一点。

| Abstract: | This paper reports that temperature distribution profiles in forward stagnation and wake region of CH 4/AIR counterflow diffusion flame have been measured by USED CARS.The pyrolysis zone of CH 4 is observed at the side with rich CH 4 in the stagnation region.The flame temperature in wake region is higher than that in stagnation region.This means there are intermediate products that did not burned completely in the stagnation region.It is proved by emission spectra of C 2 and CH 4 in wake region,too. |
