| 摘要: |
| 用三角形非结构网格及有限体积法求解Euler方程，对运动激波跨越不同截面形状的二维障碍物绕流进行了数值模拟。计算结果给出了不同时刻各流场的复杂结构，该结构与实验结果一致。计算表明用非结构算法模拟复杂外形绕流具有简单、准确的特点，并能避免尖角处非物理结果的产生。 |

| Abstract: |
| Flows of 2-D shock propagation in single or multiple baffle systems are simulated. Euler equations are solved numerically by NND finite volume scheme in unstructured triangular grids. The results show clearly the complex structure of the flowfields and compare well with experimental data. It is demonstrated that unstructured grid method can handle these complex geometries easily and avoid probable unreasonable solution near the sharp corner. |
