HPCP for Design & Analysis of Heterongeneous
Abstract
The proposed work will investigate and advance the understanding of the physics of heterogeneous energetic materials. Foundational research will be performed to enable cutting edge high fidelity, high performance, multi-scale computational techniques that will enable energetic material designers to engineer precise and controlled energy release. The primary research focus is to establish mathematical techniques and to study the mechanics of reactive flows leading to detonation, examine the fundamentals of damage of formulated explosives and to model the multi-scale shock dynamics of heterogeneous energetic materials. The fundamental modeling, numerical and algorithmic advances made will aid designers in enhancing the safety and effectiveness of energetic materials used by the Air Force. The enhanced representation and understanding of meso-scale dynamics and the connection with macro-scale dynamics of the overall explosive will aid in better definition, prediction and design of the behavior of large-scale systems (munitions, structures) that are composed of the heterogeneous materials. The methods developed here can be applied to a variety of other systems with meso-structural heterogeneities such as porous geophysical material (impact cratering, oil recovery, underground explosions), dusty gas explosions (accidental explosions in grain silos, volcanic eruptions) and in supersonic combustion of multiphase materials. Thus, the scope of the work is broad and considerable and broad impact of the developed products is expected.
