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
