Investigations on detonation shock dynamics
A detonation is a combustion-driven shock wave. Typically, a detonation will consist of an inert shock followed by a region of chemical reaction referred to as the reaction zone. Detonations have a wide variety of engineering applications, from obvious military uses to explosive welding, hard rock …

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 …

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 …

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 …

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 modelling of non-ideal high explosives
… useful work. High explosives normally burn via a detonation; a supersonic wave consisting of a shock wave coupled to chemical energy release. Detonations in conventional HE (CHE) propagate with a typical velocity of 6 - 8 km/s. Insensitive HE (IHE) and non-ideal HE (NIHE) are of particular …
