摘要:
 利用球形火焰法测量了常压下、温度为353~400,K、当量比为0.6~1.4 的丙基苯/空气预混气的层流燃
烧速率.结果表明,不同初始温度下测得的丙基苯/空气预混物无拉伸层流燃烧速率均在当量比1.1 处达到最大
值;随着初始温度的升高,丙基苯/空气预混物的拉伸火焰传播速率、无拉伸层流燃烧速率均会增加;并从不同
初始温度下的Markstein 长度与当量比的变化关系中发现,Markstein 长度会随着当量比的增加而减小,在当量比
为1.4 时出现负值;同时,Markstein 长度会随着温度的增加而略微减小.
Abstract:
 The laminar flame speeds of n-propylbenzene/air within the initial temperature range of 353—400,K
and at the equivalence ratio from 0.6 to 1.4 are measured by spherically expanding flames.The results show that the
laminar flame speed at different initial temperature reaches the maximum value at the same equivalence ratio of
1.1.And with the increase of initial temperature,both the stretched flame speed and the laminar flame speed get
higher.Due to Markstein length varying with equivalence ratio at different initial temperature,it can be found that
Markstein length decreases with the increase of equivalence ratio,and the value of Markstein length becomes
negative at the equivalence ratio of 1.4.At the same time,Markstein length decreases slightly with the increase of
initial temperature.
