Abstract
For the flow analysis of reactive compressible media involving energetic materials and deforming metallic boundaries, a HYDRO-SCCM (shock compression of condensed matter) tool is developed for handling multiphysics shock analysis of energetic and inert matters. The highly energetic flows give rise to the strong nonlinear shock waves and the high strain rate deformation of solid boundaries at high pressure and temperature. For handling the large gradients associated with these complex flows in the condensed phase as well as in the reactive gaseous phase, a new Eulerian multifluid method is formulated. The numerical methodology is described in this paper, while the extended applications and the capacity of the tool are discussed in a separate paper [J. J. Yoh and K. H. Kim, “Shock Compression of Condensed Matter using Eulerian Multimaterial Method: Applications to multi-dimensional shocks, deflagration, detonation, and laser ablation,” J. Appl. Phys. (accepted)].
