| Abstract: | A one dimensional, two phase flow model is applied to describe the dynamic compaction process of a piston driven granular bed A method of lines numerical technique is used to solve the coupled multiphase flow equations From numerical analysis, a steady compaction wave following a short time transient is predicted in the porous bed The structures of the compaction waves are also studied for various piston impact conditions |

| Keywords: | compaction wave deflagration to detonation transition two phase flow |
