TL;DR: In this article, the development of thermal instabilities during an electrical wire explosion is analyzed based on the methods of small perturbation theory, and the dispersion equations are derived that describe a relationship between the instantaneous buildup increment and the axial wave vector component.

TL;DR: In this paper, an investigation of underwater electrical wire explosions using high-power microsecond and nanosecond generators is reported, where different diagnostics, including electrical, optical, and spectroscopic, together with hydrodynamic and magnetohydrodynamic simulations, were used to characterize parameters of the discharge channel and generated strong shock waves.

TL;DR: In this article, the authors considered the electrical explosion of wires as a method for studying the behavior of materials under the conditions of fast heating and derived similarity criteria for each of the processes disturbing the uniform heating of a wire.

TL;DR: In this article, experimental and magnetohydrodynamic simulation results of nanosecond time scale underwater electrical explosions of Al, Cu, and W wires are presented, and the maximum current rise rate and maximum Joule heating power achieved during wire explosions were dI∕dt⩽500A∕ns and 6GW, respectively.
