摘要

针对稀燃条件下燃烧存在燃烧速率慢、循环变动严重的问题

研究了定容燃烧弹内点、柱、网3种电极结构下的电场对火焰形状、火焰传播距离及速率、燃烧压力的影响。结果表明:3种电极下加载电压

火焰形状均发生变形且在水平方向被拉伸; 3种电极中网电极下的电场对火焰的促进作用最大; 混合气越稀

火焰在电场中停留的时间越长

电场对火焰的影响越大。过量空气系数为1.2、1.4、1.6

网电极在加载-10 kV电压时

平均火焰传播速率比未加载电压时分别提高了66.82%、112.42%、126.16%

相对燃烧压力增大率的最大值分别为71.60%、113.55%、114.97%。

Abstract

In view of lower combustion rate and severe cyclical variation under lean condition

an experiment was conducted to investigate different effects of electric fields with the point electrode

column electrode and mesh electrode on the flame shape

propagation distance

combustion rate and pressure in a constant volume combustion bomb. The results show that the flame deforms and is stretched in the horizontal direction as applying voltage to these electrodes; the electric field with the mesh electrode affects flame most obviously; the longer the period for flame in electric field

the rarer the mixture

the greater the effect of electric field on the flame. In the case of voltage of -10 kV and excess air ratio of 1.2

1.4 and 1.6

flame propagating speed increases by 66.82%

112.42% and 126.16%

respectively. Compared with the case without applied voltage

the maximum increasing rate of relative combustion pressure rises by 71.60%

113.55% and 114.97%

respectively.
