Abstract: Equations of state of condensed species and air filling the pore space and an equation of state of the mixture are presented in a unified manner (in the form of the Mie–Grüneisen equation). Applicability of such an equation of state for air in the range of high pressures and temperatures is validated by comparisons of shock adiabats calculated with the use of this equation and available data in the literature. The thus-derived equation of state of a thermodynamically equilibrium mixture, which takes into account the characteristics of the species and their mass concentrations, offers a fairly accurate description of the behavior of a porous medium.

Keywords: equation of state, porous mixture, shock adiabat.
