Numerical simulation of thermodynamic parameters of lithium deuteride and its mixtures under shock wave loading

The results of numerical experiments on simulation of shock-wave loading of lithium deuteride using the thermodynamic equilibrium model are presented. The developed model allows us to describe thermodynamic parameters of lithium deuteride of different porosity, in a wide range of pressure using model relation, the experimental and theoretical data of lithium deuteride. Comparison of the model calculations with experimental data confirms the validity and acceptable accuracy of the used model equations. The model used makes it possible to calculate the thermodynamic parameters of lithium deuteride and its mixtures for pressures higher than 5 GPa in one-velocity and one-temperature approximations on the assumption that the pressure is identical for all phases. The calculation results have been compared with the known experimental data by different researchers.
