| 中文摘要: |
| 针对三维复杂爆炸流场的数值模拟,开发了欧拉型三维爆炸与冲击问题数值模拟软件EXPLOSION-3D,对该软件的三个组成模块即计算程序MMIC-3D、有限差分网格自动生成前处理程序MESH-3D和可视化后处理程序VISC-3D的基本理论和算法进行了讨论。以楼群中爆炸流场的三维数值模拟为例,采用该软件对大型爆炸发生后形成的爆炸场进行了数值模拟研究,得到一些有意义的数值结果,这些结果对于爆炸灾害的预防和评估具有重要的参考价值。 |
| 英文摘要: |
| In this paper, the 3D simulation software for explosion and impact is developed for the simulation of 3D complex explosion field. The theory and algorithm of the MESH-3D pre-processor code, the MMIC-3D computation code and VISC-3D post-processor code are discussed. Taking flow field of explosion in a group of buildings for example, the explosion flow field after big explosion disasters is numerically simulated using the EXPLOSION-3D software. Some important numerical results are obtained, which are of great value to the prevention and control of explosion disasters. |
