Dynamic Compaction of Porous Beds

Abstract

During the build-up of deflagration-to-detonation transition (DDT) in porous energetic materials, there is increasing dynamic compaction of the porous bed, which in turn affects the DDT build-up. To simulate the various pressures and pressurization rates that occur during DDT, a study of dynamic compaction was conducted with several different experimental arrangements, each designed to avoid direct ignition of the porous material by hot combustion products as in DDT. From those experiments, unreactive Hugoniot data were obtained for porous beds of three inert materials and a variety of energetic materials.
