Abstract: The process of diffraction of a plane detonation wave in a uniform stoichiometric suspension of small aluminum particles in oxygen on a backward-facing step in a plane channel is studied. The effect of the particle size and channel geometry on the wave pattern and wave-propagation regimes is analyzed. Analogies with the corresponding flows in gas mixtures are established. Typical differences caused by the processes of interaction between the phases are found.

Keywords: gas suspensions, heterogeneous detonation, diffraction, propagation regimes, numerical simulations.
