An Evaluation of Detonation Models

Abstract

Detona,tion lllodels of practical use for large explosive systems have been evaluated against experimental data, obtai~lecl by .AWE. The inodels considered were Chapman-Jouguet, Whit11a~m-Bdzil-Lai111~0~1r11 and Zeldovich-Neuinann-Doering. The experimental data included mea,sure~nents of c1etona.tion wa,ve propagation in various geometries of explosive , pressure a.nc1 iilitiatio~l properties. The ZND model perforins well over the widest range of problems, but not perfectly. It is not clear whether ally shortcomings are from a deficiency in the theory, ina.dequa.te a.ttention to its constitue~~t equations of state and reaction rates, or inadequate experimental cla.ta..
