A Simple Method for Calculating the Detonation Pressure of Ideal and Non-Ideal Explosives Containing Aluminum and Ammonium Nitrate

A general and simple method has been developed for calculating the detonation pressure of different kinds of ideal and non-ideal explosives containing aluminum (Al) and ammonium nitrate (AN). The new model can be applied to CHNO and CHNOFCl explosives in pure form or as mixtures as well as non-ideal mixed explosives including Al and AN. It can also be used for different plastic bonded explosives (PBXs). There is no need for any prior knowledge about the measured or calculated properties of the explosive. The only data needed are the standard enthalpy of formation and the loading density of the desired explosive. The predicted detonation pressures were compared with other predictive methods and outputs of BKWS-EOS, in both full and partial equilibrium. Different statistical parameters as well as cross validation parameters showed that the new model is precise, accurate, well-defined, and robust for predicting the detonation pressures of CHNOFCl(Al/AN) energetic materials.
