The effect of confined burning explosive abutting nonburning explosive in a variety of one-dimensional geometries has been studied by numerical simulation, demonstrating the effects of confinement, burning rate, and shock sensitivity. The model includes porous bed burning, compressible solids and gases, shock-induced decomposition with possible transition to detonation, and constant velocity ignition waves. Two-phase flow, gas relative to solid, is not allowed. Because the shock sensitivity of an explosive changes with explosive density and because such experimental data is rarely available over a range of densities, a method for the calculation of the density effect on the initial-shock-pressure, distance-to-detonation (wedge test) measure of shock sensitivity is given. The calculation uses the invariance with density of the shock particle velocity as a function of time to detonation, and the experimental data at some high density.
