| 摘要: |
| 用显式有限差分法对超燃发动机(Scramjet)的燃烧室内流场进行了数值模拟。计算中采用了MacCormack两步显格式、Baldwin-Lomax代数湍流模型以及两方程、四组分的化学反应模型。为了解决源项的刚性问题,运用点隐式方法对它作了隐式处理。 |

| Abstract: |
| Numerical simulations of chemically reacting flows in scramjet combustor have beencompleted, MacCortnack’s two step explicit scheme and Baldwin-Lomax algebric turbulence model areused. The chemistry model is a finite rate two equation model, A point-implicit method is used to treatthe source term. |
