Two-Dimensional Numerical Simulation of Deflagration-to-Detonation Transition for a Porous Explosive Using a Model of a Multivelocity Heterogeneous Medium

摘要

The model of a multivelocity heterogeneous medium is used for one-and two-dimensional numerical calculations of the deflagration-to-detonation transition for charges of a porous explosive enclosed in a casing. Calculation results are compared with experimental data. Depending on the charge diameter, different explosion regimes-detonation and low-velocity explosive transformation-are registered in both the two-dimensional calculations and experiments.
