The Cambridge/Sandia turbulent stratified flame (SwB5) is simulated with the LES and Flamelet-Generated Manifolds (FGM) combustion model. Three 3D FGM manifolds are adopted. With the purpose to examine the influence of transport properties, unity and non-unity Lewis numbers ($Le$) are included in the first two manifolds, respectively. The combined effects of non-unity $Le$ and stretch are investigated in the third manifold. Heat loss to the wall is also modeled. Good agreement is found between the simulation and experiment. The equivalence ratio, temperature and mass fractions of CO and H${}_2$ are all well reproduced in contrast with previous simulations. It is found that using non-unity $Le$ can even deteriorate the near-wall temperature modeling. Non-unity $Le$ is proposed to be crucial for the CO prediction as well, besides H${}_2$. The equivalence ratio modeling is observed to be very important, which accounts for several non-unity $Le$ effects. Flame stretch shows almost no impact on the velocity fields, whereas its effects on the species, equivalence ratio and temperature are identified, although to a limited extent for the Cambridge/Sandia flame.

剑桥/桑迪亚湍流分层火焰（SwB5）用LES和小火焰产生的歧管（FGM）燃烧模型进行了模拟。采用三个3D FGM流形。为了检验运输性质，统一和非统一路易斯数的影响（$\mathrm{大号}Ë$）分别包含在前两个歧管中。非团结的综合影响$\mathrm{大号}Ë$在第三歧管中研究拉伸和拉伸。还模拟了壁的热损失。在仿真和实验之间找到了很好的一致性。CO和H的当量比，温度和质量分数${}_2$与以前的模拟相比，所有图像都可以很好地复制。发现使用非统一$\mathrm{大号}Ë$甚至会恶化近壁温度模型。非团结$\mathrm{大号}Ë$ 建议除了H之外，对于CO预测也至关重要${}_2$。观察到当量比建模非常重要，这说明了几个不统一$\mathrm{大号}Ë$效果。火焰拉伸几乎没有显示出对速度场的影响，尽管对剑桥/桑迪亚火焰的影响有限，但火焰对拉伸物种，当量比和温度的影响已确定。
