Abstract
The processes of formation and propagation of hybrid detonation plane waves in hydrogenoxygen-argon mixtures with aluminum particles ranging in size from 3:5m to 13m with various loadings are numerically simulated. A physical and mathematical model of the reduced kinetics of hydrogen and aluminum combustion is used, taking into account the formation of solid oxide and gaseous suboxides. A stabilizing effect of aluminum particles on the flow, an increase in the detonation velocity and peak pressures and temperatures has been established. At the intermediate stage, temporary two-front configurations are formed. As the fronts propagate they merge the structures are transformed into singlefront ones. The established Chapman-Jouguet structures and their differences from gaseous detonation structures are analyzed.
