摘要：
Based on the calculations on the powdered aluminum pressure and temperature relaxation times in the detonation zone, the conventional CJ model was improved to propose a new multiphase flow model by considering the multiphase detonation products as well as the thermal disequilibrium in them. The proposed model was applied to calculate the detonation velocities of several aluminized explosives. The calculated results were compared with the existent experimental ones. And the corresponding error is less than 2%. So the calculated results by the new model are better than those by the conventional CJ model.
