| 摘要: |
| 将一股射流喷入超音速外梳是飞行器飞行控制的常用方法。本文通过应用Mac Cormack显格式和Badwin-Loinax代数湍流模型求解二维可压缩的RANS 方程，对带横向射流的绕后台阶的超音速外流场进行了数值模拟，并给出了流场的速度向量图、等压线图和等马赫线图。与无喷射的情形相比，台阶底部压力增加了一倍左右。 |

| Abstract: |
| A jet stream injecting a supersonic external flow is a common technique for the f1ight control of an aerospace vehic1e. In this paper，MacCormack explicit scheme and Baldwin-Lomax algebraic turbulent model are employed to solve the 2D compressible RANS equations for the numerical simulation of the supersonic external flow Over a rearward facing step with transverse injection. The velocity vector field，pressure contour and Mach contour of the field are given. The step bottom pressure increases by about one time as compared with the case without injection. |
