On the kinetics of chemical reactions at the detonation of organic high explosives

Abstract

The model of electrical conductivity developed earlier allows one to use electrical properties as a tool for the diagnostics of the reaction zone at the detonation of organic high explosives. The comparison of experimental data on electrical conductivity with both the results of experimental research and numerical modeling using Arrhenius kinetics is carried out. The contradiction of the thermal concept of the mechanism of the development of a chemical reaction during detonation is clearly demonstrated. An alternative based on the ideas of A. N. Dremin, J. J. Dick, C. S. Coffey, and F. E. Walker is discussed.
