| 摘 要： | 提出了一种CH4／O2在超声速气流中燃烧的6方程化学反应模型，并且用在超声速高温空气中横向喷射的二维流场进行了数值模拟验证，特别模拟了不同来流条件和壁面条件对燃烧效率的影响及CH4和空气中的氧气混合燃烧的过程。数值方法采用二阶精度的Harten-Yee隐式TVD格式，计算结果表明6方程反应模型能较好地反映CH4／O2的燃烧过程。

| Abstract: | A flow field with a sonic methane jet injected transversely into a supersonic hot air flow was simulated. The model of six elementary reactions of the methane oxygen system was verified by solving N S equations using the Harten Yee implicit TVD scheme. The effects of different boundary conditions and inlet conditions were studied and a contrast was made with the model of single reaction of the methane oxygen system. |
