Abstract

Studying the high-voltage electrochemical explosion as a control object has established a significant impact exerted by the modes of controlled energy input into a discharge channel on the efficiency of exothermal energy conversion. Dependence has been derived of the specific energy efficiency of the release of chemical energy by an exothermic mixture on the distribution of the total introduced electrical energy among successive discharge pulses. This has made it possible, based on the rules proposed here, to determine the initial conditions for the control algorithm of a discharge-pulse installation, which implements the high-voltage electrochemical explosion technological modes, providing maximum effectiveness of exothermal transformations.

It has been shown that the considerable stochasticity of processes during exothermal transformations under a mode of explosive combustion does not make it possible to use control systems that regulate only the initial conditions for an electrochemical explosion. Such systems do not ensure the preset discharge modes at each implementation. The need for ongoing control over the process of exothermal transformations has been substantiated, in order to prevent the reduction of pressure in a discharge channel below the allowable value that maintains the exothermic reaction of explosive combustion. The performed correlation analysis of the relationship between the values of current pressure in a discharge channel and the discharge electrical characteristics has revealed that there is a dense enough information interrelation between them. Therefore, it has been proposed to use, as the information signals that indirectly determine the pressure in a discharge channel, the operationally defined electrical characteristics of a discharge.

An algorithm has been built and a system has been developed to control a high-voltage discharge-pulse installation that implements a high-voltage electrochemical explosion. Control over the mode of energy input in the process of explosive transformation makes it possible to avoid the extinction of the exothermal reaction at an accidental, due to the stochasticity of the process, reduction in pressure to the maximum allowable value in the period between the discharge pulses. Due to this, the unproductive losses of an exothermic mixture are eliminated, the losses of chemical and electrical energy are reduced, and the amount of total energy released is increased, without increasing the introduced electric energy, at each implementation of a high-voltage electrochemical explosion
