TL;DR: In this article, a two-phase mixture theory is presented which describes the deflagration-to-detonation transition (DDT) in reactive granular materials, based on the continuum theory of mixtures formulated to include the compressibility of all phases and the compaction behavior of the granular material.

TL;DR: In this paper, a multiphase shock tube has been constructed to drive a planar shock wave into a dense gas-solid field of particles, which results in a spanwise curtain of spherical 100-micron particles having a volume fraction of about 20%.

TL;DR: In this paper, a hollow sphere configuration is used to simulate the dynamic and thermodynamic response of a single void centered in a field of condensed-phase energetic material, and the hot spot model includes energy balances for the pore gas and surrounding material.

TL;DR: In this paper, the TIGER code has been modified to allow systems containing up to 400 gaseous and 100 condensed constituents composed of up to 50 elements, and the Becker-Kistiakowsky-Wilson equation of state (BKW-EOS) was calibrated near C-J states using detonation temperatures measured in liquid and solid explosives and a large product species data base.

TL;DR: The mesoscopic scale response of low-density pressings of granular sugar (sucrose) to shock loading has been examined in gas-gun impact experiments using both VISAR and a line-imaging, optically recording velocity interferometer system in combination with large-volume-element, high-resolution, three-dimensional numerical simulations of these tests as mentioned in this paper.
