Detonation models are usually based on the classical Euler equations of gas dynamics under the assumption of thermodynamic equilibrium. However reported data show the Chapman-Jouguet (CJ) detonation parameters of nonideal explosives based on thermodynamic equilibrium codes are significantly different from experimental results. Based on the conventional CJ model, a new multiphase flow model, not in thermal equilibrium, was considered in this study. This approach was applied to compute the velocity of detonation for several aluminized explosives. The predictions are better than the CJ equilibrium model and are in excellent agreement with experimental data. All of the deviations for the velocity of detonation (VOD) are less than 4%.
