A mixture model for shock compression of porous multi-component reactive materials

Creators

Description

A multiphase mixture model is presented to describe shock compression of highly porous, multi-component powders. Volume fractions are represented as independent kinematic variables and thermodynamically-admissible phase interaction constitutive models are formulated in the context of a three phase system. Numerical solutions of the multiphase flow equations simulated impact on a porous layer of mixed powders of Al and Fe2O3. The multiphase model predicts dispersive compaction waves which have features similar to observed time-resolved pressure measurements
