Detonation properties of tetranitromethane–methanol mixture

Abstract

An experimental study of the reaction zone structure and stability of detonation waves was performed for tetranitromethane–methanol (TNM–M) mixture using a velocity interferometer system for any reflector (VISAR). At the near stoichiometric concentration of methanol, it was observed that the amplitude of Von Neumann spike decreases significantly, whereas the detonation parameters increase. The instability of detonation waves in TNM–M mixture was shown, both with respect to one-dimensional longitudinal perturbations and to the curvature of the front leading to the formation of the cellular structure. The dependence of detonation velocity of TNM–M on the diluent concentration and limits of detonation propagation were found.
