T1 Random Packs and Their Use in Grain-Scale Modeling, with Applications to Energetic Materials JF International Journal for Multiscale Computational Engineering JO JMC YR 2010 FD 2010-11-29 VO 8 IS 5 SP 473 OP 487 K1 random packs K1 energetic materials K1 convective burning AB In recent years, we have constructed closely packed spheres using the Lubachevsky-Stillinger algorithm to generate models of heterogeneous solid propellants. Improvements to the algorithm now allow us to pack nonspherical shapes for modeling heterogeneity in complex energetic materials such as plastic-bonded explosives and pressed gun propellants. In this paper, we review the packing algorithm and present selected results, including higher-order statistics, along with preliminary results of convective burning through a porous medium.
