| 摘 要： | 由Level set方法确定湍流预混燃烧火焰面的位置,考虑CHEMKIN库详细化学反应机理,通过PDF方法建立湍流预混燃烧数学模型,计算组分浓度和温度在火焰内部分布。以矩形突扩燃烧室为例,模拟甲烷/空气预混燃烧的平均火焰位置和火焰内部温度、浓度分布,计算结果与实验结果吻合良好,表明此模型能较好模拟湍流预混燃烧。

| Abstract: | Using the Level-set method and considering the detailed mechanism of chemical reactions,the position of flame surface is identified and the distribution of concentration and temperaturein the flame is calculated with the flamelet model.Taking Sudden-expansion combustor as an object of simulation,authors simulate the averaged position of flame surface and present the distribution of temperature in CH_4/Air premixed combustion flame.The satisfactory agree between calculating results and experimental data show that the flamelet model is realiable. |
