Dissociation of Shock-Compressed Liquid Hydrogen and Deuterium

Compression in a shock wave is followed by a large number of nonequilibrium processes, such as excitement of internal degrees of freedom, chemical reactions, and establishment of chemical equilibrium. Thermodynamic parameters of shock-compressed liquid hydrogen and deuterium are calculated on the basis of the developed model of the equation of a state (EOS) of two-component fluid mixtures with use of potential of intermolecular interaction of Exp-6. Comparison of the calculated parameters of a quasiequilibrium condition of the two-component mixtures which are formed as a result of dissociation at strong compression in a shock wave with experimental data allows concluding that the offered theoretical model EOS reliably describes thermodynamic properties of two-component fluid mixtures in the wide range of pressure and temperatures at chemical equilibrium.
