Modeling the detonation propagation in nanodisperse mixture of aluminum particles in channels with expansion

Abstract

The problem of detonation propagrtion in channels with linear expansion filled with nano-sized alumunium mixture dispersed in oxigen was investigated. Transition from diffusion to kinetic regime of combustion with variation of the activation energy was taken into account in the description of the chemical reactions. Specific features of detonation failing in subcritical regimes and propagation in critical regimes have been revealed. The detonation propagation was found to be more unstable then in microdisperse aluminum suspensions.
