The results of numerical modeling of cellular detonation of hydrogen-air mixtures with additives of dispersed micron-sized aluminum particles are presented. The effect of particle size and loading on the process characteristics is established. The variety of cellular detonation forms is shown: with a regular and irregular cell, with oblique cells and an inclined front, depending on the distribution of particles in space. The development of combined instability with a layered distribution of particles is demonstrated. The obtained results allow us to consider additives of aluminum particles as a control factor for the implementation of different detonation modes in hydrogen-containing hybrid mixtures. Keywords: Detonation, gas suspensions, hydrogen-air mixture, aluminum particles, numerical modeling.
