采用20步的反应机理并应用多分量扩散进行了模拟计算.讨论了Kolmogorov类型能量级串和多重涡效应导致的局部熄火现象.对于中心线发展量与条件统计量的计算符合实验数据.用一维全尺度湍流(ODT)模型对微量组分OH基和O基进行计算,给出了随着火焰发展自由基生成和消耗的信息.
The 20-step reaction mechanism and multicomponent diffusion were applied in the simulation. The Kolmogorov-type cascade was captured and the localized extinction due to the multiple eddies effect was discussed. Predictions of the centerline evolution scalars and the conditional statistics were compared with measurements and reasonable agreements were obtained. One-dimensional turbulence (ODT) predictions of minor species such as OH and O were presented. The discussion of OH and O gives the information of radical production and consumption with flame evnlution
