    Abstract
  • To explore the afterburning reaction of TNT explosive, the underwater explosion method and an experimental device designed to enhance the afterburning reaction of explosives were used to investigate the energy output structure, and the afterburning reaction energy in different ambient atmosphere was calculated.The experimental data of afterburning reaction was simulated by using Miller energy release model.The results show that the experimental device filled with oxygen or air can increase the afterburning reaction energy output of TNT explosive significantly.The measured afterburning reaction energy increases with the increase of the content of oxygen, and in the studied range, the afterburning reaction energy reaches the maximum value of 4.90 kJ/g, but does not reach the theoretically maximum value.The computed shock wave pressure histories agree with the measured ones well, which indicates that the Miller energy release model is practicable.
