| 摘要: |
| 采用时间和空间二阶精度的TVD格式数值模拟了二维楔的水平相对非定常运动过程与定常组合体流场。在数值模拟时, 我们采用了重叠网格技术。这种方法大大减轻了复杂外形的网格生成工作量, 而且重叠网格间可以有相对运动, 这使我们对相对运动物体流场的数值模拟简便易行。 |

| Abstract: |
| A two-dimensional TVD scheme with second order accuracy in space and time is used to simulate the horizontal relative motion flowfield between wedges. Grid-embedding technique is applied to calculate the unsteady flowfield. This technique simplifies the construction of computational grids about complex geometries and allows relative motion between embedded grids. |
