N2 - This chapter mainly reviews the physics and applications of exploding conductors via pulsed current in air/water. Most of the mentioned work is performed in Beijing Institute of Technology or Xi’an Jiaotong University in the last few years. Besides a high-density (thermal) plasma source, the electrical explosion driven by a pulsed current in gaseous/liquid medium, is also indispensable in opening switches, nano-material synthesis, shock-wave sources, etc. Firstly, simulation and experimental methods for electrical explosion were briefly introduced. Secondly, effects of the medium and physical characteristics of the electrical explosion plasma are revealed by spatial–temporal diagnostics. Instabilities and ionization of the partial vaporized metal wire are understood, and their effects on fluid dynamics (shock and bubble) are depicted. Thirdly, explosion or implosion via wire and/or wire array are discussed for generating strong shock waves in water. In addition to this, the related applications including reservoir stimulation, explosion effect simulation, and nanomaterial preparation are introduced. Finally, the key points and difficulties in future research are put forward in the aspects of fundamental research and industrial applications. It is anticipated that this chapter could provide an outlined, but up-to-date image of wire explosion research (in a medium) to readers and act as a reference for scholars in related domains.
