Abstract

Open Burning/Open Detonation (OB/OD) has been widely used for demilitarization of expired explosives. However, OB/OD effects a variety of hazardous damages to environment. Therefore, using incinerators to treat expired explosives is required instead of OB/OD. To guarantee the safety of these demilitarization methods, the blast wave of the explosives should be previously recognized to evaluate the impact of detonations. Although various materials are used to produce explosives, most researches have focused on trinitrotoluene (TNT). Other representative explosives such as research department explosives (RDX) and high melting explosives (HMX) are seldom studied in the literature. Therefore, our aim was to understand the blast wave of three materials under different geometry throughout simulations. To improve accuracy and reduce computational time, a zoning technique with Euler-Lagrange coupling method was used. Due to limitations and difficulties of detonation experiments, simulations were verified by theoretical models. In case of semi-confined bunker, the simulation results were compared with experimental data, showing a close match. As a result, cylinder type is the safest incinerator among semi-confined bunker, cylinder, and cube incinerators, in terms of the blast wave.
