Application of Surface Decomposition Kinetics to Detonation of Ammonium Nitrate

摘要

Kinetic rate data for the linear surface gasification (pyrolysis) of ammonium nitrate is used in conjunction with the Eyring grain-burning theory to calculate the detonation reaction time for ammonium nitrate. A new grain-burning mechanism is presented which results in a reaction time for detonating ammonium nitrate that is consistent with the one calculated by means of the nozzle and curved-front diameter theories. The implications of the new model with respect to low-velocity detonations in mixtures of granular explosives is deiscussed.
