Abstract:
In this paper we study the conditions of self-sustaining wave propagation upon combustion of a monofuel particle suspension in vacuum. We employ a two-velocity model of the flow of reaction products behind the detonation wave (DW). Essentially new conditions behind the DW front are obtained that ensure its propagation with a velocity higher than the velocity of ideal Chapman–Jouguet detonation in particle suspension in vacuum. The results agree qualitatively with the experimental data on the detonation velocity of lead azide in vacuum.
