000013856 520__ $$2eng$$aThe effect of both one- and two-dimensional spatial heterogeneities on the propagation of a detonation wave governed by single-step Arrhenius kinetics is computationally examined in this study. The reactive medium consists of a calorically perfect gas. The spatial heterogeneity can be introduced to the reactive medium as a piecewise-continuous distribution (e.g., Gaussian or step function) in the initial density or concentration of the reactant. In one-dimensional simulations, the resulting detonation velocity will be compared with that of an ideal Chapman-Jouguet detonation in a homogeneous medium with the same amount of energy release. The influence of the spatial heterogeneity on the detonation limits will also be computationally investigated by simulating two-dimensional detonations experiencing losses due to lateral expansion.
