Modeling deflagration-to-detonation transition in granular explosive pentaerythritol tetranitrate

Sáenz, Juan A.; Stewart, D. Scott


Based on an approach suggested by Stewart et al. [Phys. Fluids6, 2515 (1994)] we develop a model to simulate deflagration-to-detonation transition (DDT) in pentaerythritol tetranitrate (PETN) powders. The model uses a continuum mechanics formulation of conservation laws for a mixture of solid reactants and gas products, written in terms of mixture quantities plus two independent variables used to account for exothermic conversion of solid reactants into gas products, and compaction associated...[Show more]
