| 摘 要： | 利用微重力条件下向外传播的球形火焰,对贫燃极限附近甲烷/空气预混火焰的层流燃烧速度进行了测量,得到当量比从0.512(本文微重力实验中测定的可燃极限)到0.601范围内的零拉伸层流燃烧速度,并与前人实验数据和使用3种化学反应动力学模型的计算结果进行了比较.本文实验结果与已有的微重力实验数据非常接近,而其他研究者在常重力...

| Abstract: | Outwardly propagating spherical flames in microgravity have been employed to determine the laminar burning velocities of near-limit fuel-lean methane/air flames.Resulting data were reported for methane/air mixtures over the specific range of equivalence ratio that extended from 0.512(the flammability limit found in the microgravity experiments) to 0.601.Present measurements of unstretched laminar burning velocities were in good agreement with the unique existing microgravity data set.Most of previous 1g exp... |
