A multicomponent one-velocity model for inert and reactive porous mixtures exposed to explosive detonation

The paper provides a multicomponent one-velocity model for numerical simulation of the behavior of inert and reactive porous mixtures exposed to explosive detonation. A system of equations describing the nonstationary adiabatic motion of both inert and reactive mixture components is presented. The relations for achieving mechanical equilibrium in a multicomponent mixture exposed to explosive detonation are considered within the framework of an elastic-plastic medium. To simulate explosive detonation, the upper part of the ampoule is exposed to pressure in an axial direction and the lateral side of the ampoule is exposed to pressure in a radial direction.
