Abstract

This study investigates the pneumatic dispersion of aziridine, exo-tetrahydrodicyclopentadiene (JP-10), isopropyl nitrate, and nano-aluminum mixtures using Eulerian multiphase simulations and experimental validation (error < 8%). The results reveal that nano-aluminum introduces a unique “delayed enhancement” effect: it suppresses initial core velocity but significantly boosts overall cloud momentum in later stages. This optimizes spatiotemporal energy distribution by synchronizing kinetic and chemical energy release during secondary detonation, facilitating efficient conversion of chemical to kinetic energy. Ultimately, this study elucidates one of the underlying mechanisms of the enhanced detonation effects of nano-aluminum in fuel–air explosive clouds.
