| 摘 要： | 采用Bilger提出的条件矩模型对CH4－CO2湍流射流扩散燃烧进行了数值 模拟。对于湍流流和混合分数场采用k-ε-f-g模型，对于组分浓度场采用条件矩模型的抛物线型方程。将速度场、温度场和主要组分（CH4和CO2）浓度场的模拟数据与美国Sandia国家实验室的实验数据进行了对照。结果表明条件矩模型能够较好地反映扩散燃烧的火焰结构，是湍流燃烧模型研究的一种值得探讨的有前途的方法。

| Abstract: | Conditional moment closure(CMC)model proposed by Bilger is used for simulation of GH 4 Air diffusion combustion and its NO x formation in this paper. CMC is characterized by uncoupling the co relation of non linear source in chemistry and non uniform in flow. The results of the comparison of the predictions with experimental data demonstrate that CMC has good performance in the predictions of the fields of velocity, temperature and main component (CH 4 and CO 2) concentration. Conditional moment closure turbulent combustion model is worth studying and has a bright prospect. |
