Wood-Kirkwood theory reaction zone thickness determinations and computer simulations of wave curvature experiments of two sets of explosives are presented. One set included explosives composed of RDX with different crystal quality characteristics. The other set of explosives was composed of monomodal explosives made from fine, coarse and very coarse sieved RDX and bimodal explosives made from combining the fine and very coarse RDX. The calculated reaction zone thickness was found to be greater for explosives with higher RDX crystal quality and for those of higher mean particle size. A simplified two-term ignition and growth reactive model parameterized by embedded gauge experiments was used in CTH hydrocode simulations of the wave curvature experiments for the explosives where crystal quality was varied. The simulations under-predicted the axial position lag seen in experiment and predicted as seen in experiment, that the explosive containing the higher quality crystals had a greater axial position lag.
