- The data reported shows that the Chapman-Jouguet (CJ) detonation parameters of non-ideal explosives calculated from existing thermodynamic computer codes are significantly different from experimental results. We use CJ detonation theory to present a new approach predicting detonation pressure and velocity of aluminized explosives by thermodynamic detonation theory. There is no need to use the assumption of full and partial equilibrium of aluminum powder in reaction zones in the new approach. In this work the best agreement with experimental data was obtained by adjusting the parameter k in the Becker- Kistiakosky-Wilson equations of state (BKW-EOS). The detonation pressure and velocity values calculated by the present method agree well with the experimental results. All of the deviations for the calculated pressures of aluminized explosives are less than 9% and those for the detonation velocities are less than 7%.
