A Computational Study on the Detonation Velocity of Mixtures of Solid Explosives with Non‐Explosive Liquids

Abstract

According to Urbanski's finding in a solid explosive with a density of less than the theoretical maximum density (TMD), the detonation velocity increases if the air contained in the explosive gets replaced by a non‐explosive liquid. In order to quantify this observation, the detonation velocities for RDX in combination with ten non‐explosive liquids were calculated using the EXPLO5 code (V6.05.04). It could be shown that pressing out the air of a high‐explosive powder and replacing the voids with a non‐explosive liquid such as ethylene glycol, water or glycerin helped to increase the final detonation velocity.
