On Detonation Diffraction in Condensed-Phase Explosives
A recently proposed higher order theory including shock acceleration effects for detonation shock dynamics (DSD) is evaluated for PBX-9502. Comparisons of detonation diffraction in PBX-9502 are made between experiment, multi-material simulations using the calibrated equation of state and reaction …

Instability of steady and quasi-steady detonations
… and dynamic behavior of steady and quasi-steady detonation theories are investigated through linear stability analysis and numerical simulation. A general, unsteady, three-dimensional formulation of the reactive Euler equations in a shock-fitted reference frame is derived. The formulation is …

Detonation shock and ignition dynamics in condensed phase explosives
We investigate the ignition and dynamics of detonation waves in condensed phase explosives using direct numerical simulations and asymptotic analysis. We develop a model to simulate deflagration to detonation transition in pentaerythritol tetranitrate powders. The model uses a continuum mechanics …

Parallel algorithms applied to problems in two dimensional detonation shock dynamics
… of a parallel extension for a two-dimensional Detonation Shock Dynamics code, and to demonstrate how it can be applied for solving engineering problems in detonation physics. Detonation Shock Dynamics (DSD) is an asymptotic theory that describes the evolution of a multidimensional curve …
