摘要: 采用NND差分格式,同时利用点爆炸解作为计算初值,对圆柱形容器内部的二维轴对称非定常流场进行了数值模拟,清楚地反映了内部流场的变化过程,得到了容器壁面上各点的压力-时间关系。对计算结果进行了讨论,与文献中结果作了比较。

Abstract: The axial transient flow within a cylindrical container is simulated numerically using a NND finite difference scheme. The self-similar solution of the point-source explosion problem is obtained to give initial conditions. Shock loads at the inner wall of the vessel and the development of the flow field are deterimined through this numerical simulation. Results are discussed and compared with experimental data in other literatures.

Key words: explosion, finite difference method, transient flow, numerical simulation
