Detonation properties of the mixture of tetranitromethane/nitrobenzene

Abstract The experimental investigation of the reaction zone structure and stability of detonation waves was performed for the mixture of tetranitromethane/nitrobenzene (TNM/NB) by a VISAR laser interferometer. At the near stoichiometric concentration of NB, it is observed that the amplitude of von Neumann spike decreases significantly, whereas the detonation parameters increase. The instability of detonation waves in the TNM/NB mixture is shown, both with respect to one-dimensional longitudinal perturbations and to the curvature of the front, which results in the formation of a cellular structure. The dependence of detonation velocity of TNM/NB on the diluent concentration and limits of detonation propagation were found.
