Abstract
A new empirical method for predicting detonation pressure of various types of organic and inorganic explosives is presented. The method identifies detonation products by the product that releases the maximum amount of heat per oxygen atom. The proposed model provides accurate and reliable estimates of detonation products compared to existing models. Using these identified products, detonation parameters such as the number of moles of gaseous products, their average molecular weight, and the maximum heat of detonation are calculated. A power-law relationship is established between the detonation parameter and experimental values of detonation pressure for different explosives. Unlike other models, the detonation pressure calculated by the new model agrees well with the experimental values for organic and inorganic explosives. These results indicate that detonation pressure predictions based on the new model are simple, accurate, and more reliable than those based on existing models, thereby contributing to the development of environmentally friendly, high-performance explosives.
