A Simple and Reliable Method for Predicting the Detonation Velocity of CHNOFCl and Aluminized Explosives

A reliable method is introduced for predicting the detonation velocity of CHNOFClAl explosives through suitable decomposition paths. The predicted decomposition products are used to estimate the heat of detonation (decomposition) and the detonation velocity. For non-ideal aluminized explosives, the Chapman-Jouguet detonation velocities are significantly different from those expected from existing thermodynamic computer codes for equilibrium and steady state calculations. The predicted detonation velocities give more reliable results for CHNO explosives than one of the best available empirical methods over a wide range of loading densities. The new model provides better agreement with respect to experimental values for aluminized explosives than the computed results from the BKWS equation of state using full and partial equilibrium of aluminium.
