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 the application of multi-component diffusion are used to simulate the calculation.The partial flameout caused by the Kolmogorov-type energy series and the multi-vortex effect is discussed.The calculation of the development of the central line and the condition statistics is in accordance with the experimental data, Dimensional full scale turbulent flow (ODT) model was used to calculate the OH and O groups of trace components, and the information about the formation and consumption of free radicals with flame development was given.
