通过对预混乙炔-空气爆燃火焰在平板狭缝中的传播与熄灭过程进行试验研究,分析临界火焰传播速度、狭缝高度和熄灭长度之间的关系。实验结果表明,当狭缝高度一定时,临界火焰传播速度越大,熄灭长度越大,熄灭长度与临界火焰传播速度近似呈正比例关系。在相同的临界火焰传播速度条件下,随着狭缝高度的增加,熄灭长度值迅速增大,说明狭缝高度对预混火焰的传播与熄灭有显著影响。
- Abstract:
-
Propagation and quenching of premixed Acetyleneair deflagration flames in narrow channels are studied experimentally, and the relationships of critical flame propagation speed, channel height and quenching length are analyzed. Experimental results show that, as channel height is given, quenching length is proportional to critical flame propagation speed approximately. At given critical flame propagation speed, quenching length increases evidently with increasing channel height. It shows that channel height has a marked influence on flame propagation and quenching. The computed results show the same conclusion. The computed results are consistent with the experimental results as a whole.
