ON THE RELATIONSHIP BETWEEN THE NON-REACTED AND DETONATION PRODUCTS EQUATIONS OF STATE FOR AN EXPLOSIVE

In many reactive flow models for explosives, the non-reacted and detonation products equations of state are treated independently, each just matching some appropriate experimental data. As a result, the two equations of state usually conflict in some parts of the pressure-volume-internal energy space. This paper suggests a general criterion for the relationship between the two equations of state and develops more specific criteria for the often used Mie-Gruneisen form of equations of state.
