| 摘 要： | 将一股射流喷入超音速外流是飞行器飞行控制的常用方法。本文通过应用MacCormack 显格式和Ba(?)dwin-Lomax 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 techniquefor the flight control of an aerospace vehicle.In this paper,MacCormackexplicit scheme and Baldwin-Lomax algebraic turbulent model are employed to solve the 2D compressible RANS equations for the numerical simulation ofthe supersonic external flow over a rearward facing step with transverse inje-ction.The velocity vector field,pressure contour and Mach contour of thefield are given.The step bottom pressure increases by about one time ascompared with the case without injection. |
