Abstract

In order to study the response of explosive under different heat temperature and the corresponding law, in this article, it adopted RDX as the base of high explosive with the heating rate of 1 °C/min, the thermostat control technology was used for different environment temperature heat test and carried out the numerical simulation with software FLUENT. It turned out that the cook-off temperature had important effect on thermal decomposition of explosives. Under the heating rate condition of 1 °C/min, when the constant temperature reached 178 °C, experiments with high explosives occurred the self-heated reaction, eventually leading to the ignition; with the increase of explosive charge, explosive heat detonation critical temperature was gradually reduced.

Key words： explosive; slow cook-off; critical temperature; thermal explosion
