A Eulerian Level Set‐based Framework for Reactive Meso‐scale Analysis of Heterogeneous Energetic Materials
Heterogeneous energetic materials such as plastic‐bonded explosives and pressed explosives are integral parts of many engineering systems such as propulsive devices, munitions and explosive actuators. This chapter presents a numerical framework to perform highly resolved reactive meso‐scale simulations of experimentally obtained microstructures of heterogeneous energetic materials. Meso‐scale simulations can reveal important physical mechanisms that can improve the current understanding of the sensitivity behavior of heterogeneous energetic materials. The chapter establishes a Cartesian grid‐based Eulerian framework to perform highly resolved reactive meso‐scale simulations on experimentally obtained image microstructures of heterogeneous energetic materials.It presents the details of the image to level set‐based numerical framework. In the current Eulerian framework, the governing equations comprise a set of hyperbolic conservation laws corresponding to the conservation of mass, momentum and energy. The image processing algorithm operates on the image intensity field and generates a level set representation of the material interfaces.
