The purpose of the study is the development of scientific bases of energy transformation during an underwater high-voltage electrochemical explosion in restricted volumes, development of computational algorithms for the parametres of the combined electrodischarge energy sources with use of the HVEE with respect to the needs of different certain discharge-pulse technologies.Experimental research of electrodynamical, energy and hydrodynamical characteristics dependencies of the high-voltage electrochemical explosion in a confined volume with respect to initial and boundary conditions is conducted. It is determined that in the case when the time of reflected pressure wave's arrival at the channel exceeds 40 µs, electrodynamical and hydrodynamical characteristics of the high-voltage electrochemical explosion in a confined volume are identical to analog characteristics in a non-confined volume. It is proved by experiments that during the high-voltage electrochemical explosion in a confined volume, on condition that the vapor-gas hollow is commeasurable with the chamber volume in which the high-voltage electrochemical explosion is realized, the key power factor is quasistatic pressure determined by the vapor-gas hollow propagation. It is shown that during the high-voltage electrochemical explosion both in a small and an infinite volume, electrode system mass unit combustion efficiency in the channel of the high-voltage electrochemical explosion depends on electrodynamical characteristics. Nevertheless, during the high-voltage electrochemical explosion implementation in a small volume, further experimental research and development of a three-dimentaional model describing the phenomena occurring in closed chambers of a small volume in a millisecond range will be requested on purpose to specify the functional dependency of specific efficiency of exothermal transformations Product Description popup.authors Барбашова Г.О.
