Abstract
A thermodynamic program that can estimate the detonation characteristics of energy materials using KHT and KH equations of states (EOSs) has been developed. The molecular constants and thermodynamic data for gaseous species for detonation products were referred to the database in the KHT code. Three empirical parameter sets for KH EOS were examined and the results were compared with the results of KHT EOS. The empirical parameters of KH EOS, which were derived logically in 1952, could reproduce the results of KHT relatively well in the high pressure region. Moreover, the improved empirical parameter set of KH EOS was obtained by fitting on the results of KHT EOS. As a result, the C-J isentropic lines obtained using KHT and KH EOSs were equivalent.
