Constitutive model of shock-induced chemical reactions in inorganic powder mixtures

Abstract

An improved hydrodynamic model has been developed for analysis and interpretation of shock-induced chemical reactions in inorganic powder mixtures. Attention is focused on the interaction of hydrodynamic flow with the thermodynamic changes associated with chemical reactions such as specific volume, specific internal energy, and material properties. Predictive capabilities of the model have been illustrated using experimental shock wave profile data involving Ni-Al and Al-Fe2O3 mixtures.
