Short Abstract: We present preliminary results of 2D numerical gasdynamic study of detonation cell structure in hybrid two-phase hydrogen-air mixture with suspended aluminum particles of different sizes. The results are in qualitative agreement with observed effects of particles on detonation cell structure and improve existing knowledge of detonations in hybrid mixtures with aluminum particles. Better quantitative agreement with the experimental data is attempted by improving description of kinetics of gaseous reactions and effect of particles on the heat release rate.
