Reactive Flow Modeling Of Small Scale Detonation Failure Experiments For A Baseline Non-Ideal Explosive, David E. Kittell, Nick R. Cummock, Steven F. Son

Purdue Energetics Research Center Articles

Small scale characterization experiments using only 1–5 g of a baseline ammonium nitrate plus fuel oil (ANFO) explosive are discussed and simulated using an ignition and growth reactive flow model. There exists a strong need for the small scale characterization of non-ideal explosives in order to adequately survey the wide parameter space in sample composition, density, and microstructure of these materials. However, it is largely unknown in the scientific community whether any useful or meaningful result may be obtained from detonation failure, and whether a minimum sample size or level of confinement exists for the experiments. In this work, it …
