Calculation of the Shock Adiabat of Powder Mixtures With a Glance a Dependence of the Grüneisen Coefficient on Temperature

In work the model, allowing to calculate a shock adiabat of a powder mixture is offered. In model dependence of Grüneisen coefficient in an explicit form only from temperature is considered. Comparison of effects of calculations with known experimental effects of different authors for powders and intermixtures of various compositions is made. It is shown that calculation yields the good consent with experiment for two- and ternary (on number of condensed phases) intermixtures for all experimental data known to authors.

Equation of state for liquid water

The equation of state for water (EOSW) in Mi–Gruneisen form with Born–Mayer potential for densities less, than 1 g/cm^3 is developed. The equation is applicable to moderate and high pressures (up to 2·10^12 Pa), in particular, to explosive and static pressures in the range of densities from 0.7 to 3.8 g/cm^3 . The equation for the Gruneisen coefficient that depends not only on the specific volume but also on the temperature is received. The proposed method by the experimental data for dependencies on specific volume and temperature the heat capacity and isochoric temperature coefficient of pressure increase allows to calculate the Gruneisen coefficient and the internal heat energy.
