Detonation Modeling of High Explosives Using WK Theory

In this article, the detonation wave propagation in the ideal and non-ideal high explosives has been studied and compared. This study is performed utilizing the Wood-Kirkwood theory (WK theory), which is valid for slightly curved self sustained detonations. Utilizing this model, a relation between detonation velocity and the front curvature is obtained. In this study, it has been shown that non-ideal explosives are poorly modeled by Chapman-Jouguet (CJ) theory. Comparison of the results of WK model with empirical data reveals that WK model has good accuracy in modeling detonation propagation in non-ideal explosives, especially for small curvatures. The present study shows that of the accuracy of state equations, the employed burning rate, their calibration, and also the mixture rules influence the results considerably.
