Abstract. A multidimensional implementation of DSD, formulated with the level set method, is
applied to track the propagation of a detonation wave in a heterogeneous explosive consisting of an
array of inert cylindrical obstacles with a liquid explosive in the interstitial space. With the Huygens
assumption, the average detonation velocity through the explosive is less than that for the liquid
explosive alone, due to the increased path length. When the normal detonation velocity is assumed to
depend on front curvature, there is an additional, smaller reduction in the detonation velocity, which
depends on the cylinder material. The detonation velocity deficits obtained in the computations are of
the same order as those observed experimentally for a heterogeneous explosive consisting of a packed
bed of spherical inert beads saturated with sensitized nitromethane. The DSD computations are
relevant to the experimental results in the large-bead limit in which the pore dimension is large enough
