Numerical modeling of thermodynamic parameters for mixtures with a few-parameter equation of state of their components

Abstract

The results of numerical experiments on shock-wave loading of heterogeneous mixtures including tungsten and copper as a component are presented. Thermodynamically equilibrium model with a modified equation of state is used for modeling of thermodynamic parameters of pure materials and mixtures. The thermodynamic parameters for copper of different porosity are calculated for few-parameter equation of state, values of compression ratio and temperature along the shock adiabat are determined; the value of heat capacity at normal pressure is calculated. The results of calculations are compared with the known experimental results of different authors. The calculation of thermodynamic parameters under shock-wave loading for mixtures including tungsten and copper as a component is performed.
