Effects of coupling radiation on detonation parameters of inert explosive: a MC+thermodynamics study

Abstract

Influences of neutron & γ mixing radiation field on decomposition speed and detonation parameters of long-term storage explosive molecular have been performed by a combined MC+thermodynamics method. The results show that energy deposition of neutron & γ transport in explosive components has a negligible effect on the decomposition speed, detonation speed and detonation pressure, but it significantly improves the detonation temperature of the explosive. The findings can be helpful for deeply understanding aging mechanisms for long-term storage explosive component, and improving its safety and reliability.
