Analysis of Multi-Scale Phenomena and Transients in Explosives and Complex Energetic Systems
Abstract
This report summarizes the activities of a 3-year grant and 6 month extension supported by the Air Force Office of Scientific Research. The main topics covered by our investigations, are described succinctly as: (1) Complexity and meso-scale investigations of condensed explosive and reactive materials that include dynamical interaction of reactive flow at the scale of the microstructure of the material. We developed concepts related to the multi-scale statistical design of high energy density materials and specific modeling approaches required to described metal loaded, condensed phase explosives, with a reduced detonation theories. (2) Theory and simulation for porous energetic explosives and multiphase reactive materials. This included asymptotic derivation of a theory of detonation shock dynamics for a porous energetic materials, and the development of entirely new models that can be used to describe non-classical detonation phenomena observed in reactive materials (sometime referred to as 'solid state detonation'.) (3) Linear and nonlinear theory for stability of detonations, formulated in the shock attached frame. The grant also supported the completion of two comprehensive review articles on detonation stability theory and detonation shock dynamics.
