Abstract

When studying the structure of the reaction zone in detonation waves of powerful explosives, one usually measures the mechanical characteristics of the flow - the distributions of particle velocity, pressure or density. Experience shows that on such profiles, it is rather difficult to distinguish the chemical reaction zone. These distributions, as a rule, are distorted when the flow interacts with measuring units. In this paper, we consider the prospects of an alternative method of electrical conductivity, which is largely free from the indicated disadvantages and has a number of advantages. The correlation between the region of high electrical conductivity and the reaction zone is substantiated by comparing the results of traditional methods and conductivity profiles.
