In this talk we present results from a numerical study on the structure and stability of detonations in mixtures of gases and solid particles. Cases with both reactive and inert particles are considered. First, the two-phase flow model is described and the various assumptions that it is based upon are discussed. Next, we present an analysis of the steady-wave structures that are admitted by the flow model. Subsequently, numerical results for both 1-D and 2-D detonations are presented and discussed. These results predict that the mass, momentum, and heat transfer between the two phases result in in detonation structures that are substantially different from those observed in purely gaseous flows. The presentation concludes with a discussion of the effect of certain important parameters, such as particle reactivity, particle volume fraction, and particle diameter.
