Abstract: Detonation Shock Dynamics (DSD) can be used to model the eects
that shock curvature has on detonation speed Dn(). At the edges of the
explosive, Dn() is supplemented with boundary conditons. By direct numerical
simulation (DNS), we study how the reaction zone interacts with the edge. DSD
theory has been integrated with the level-set method of Osher & Sethian and
the Los Alamos DNS code Mesa to create a powerful tool for simulating complex
explosive-containing systems.
Key words: Detonation, Curvature eect, Edge interactions, Mach re ection
1. Introduction
To accurately predict the propagation of detonation through an explosive, one
needs to model the physics that occurs on the chemical reaction-zone scale r.
