| 摘要: |
| 采用二阶TVD格式的有限体积法偶合Baldwin-Lomax代数湍流模型求解雷诺平均Navier-stokes方程，数值模拟了二维矩形等截面隔离段中的流动现象，很好地模拟出由激波/附面层干扰所形成的复杂的激波串流场结构。计算结果与国外有关文献的结果进行了比较。 |

| Abstract: |
| A finite volume method is used to simulate the shock train flows in a generic two-dimensional constant area isolator. Isolator is an important components of Dual-Mode scramjet. The interaction between a normal shock wave and a boundary layer along a wall surface in isolator compressible flows causes a very complicated flow. The interaction region including a shock train and a mixing region in it is referred to as “pseudo-shock”. The finite volume method is used to solve the 2D Reynolds-averaged Navier-Stokes equation coupling the Baldwin-Lomax zero-equation turbulence model. In the numerical procedure, LUSGS method and TVD scheme are used. The numerical results simulate commendably the topology structure of the flows. |
