Summary: This study utilized the heat released by the alumino-thermic reaction between Al wire and CuO powder to enhance the shock wave generated by underwater electrical wire explosion. Experimental and numerical simulation results showed that the coating layer on the Al wire delayed the restrike of the exploding wire, resulting in an improved shock wave amplitude and steeper rising edge.

Summary: The acceleration of a target by employing the shock compression and water flow generated by the underwater electrical explosion of a wire array is an efficient approach, with target velocities of up to 1360 m/s measured. The experimental, numerical, and analytical modeling results demonstrate that a temporally unmovable barrier between the exploding array and the target increases pressure and leads to higher shock velocity in the target, providing insight into the phenomenon.

Summary: The parametric relationships between underwater shock waves and electrically exploded wire under different charging voltages of a generator were investigated. The contributions of vaporization and current restrike to the shock waves were examined through various diagnostic methods. The experiment revealed that the relationship between electro-physical and shock wave parameters becomes more complex as the charging voltage increases.

Summary: The study examined the uniformity of electric current distribution in a wire array and its unstable behavior during underwater electrical explosion. Experimental results showed that deviations in wire dimensions can lead to unbalanced current distribution, affecting the thermodynamic state evolution and current distribution behavior during the explosion process.

Summary: The damage characteristics of underwater explosion-generated shock wave, shaped charge projectile (SCP) and bubble into double-hull structure are analyzed. The protection of fiber metal laminates (FML) is discussed. The results show that the FML can prevent the tearing and penetration of shaped charge projectile, while the bubble load is effectively stopped by coated polyethylene (PE), indicating a great protection performance.

Summary: This study experimentally investigates a Cu planar wire array (PWA) in air and water, showing that PWA has higher electric power peak, faster vaporization and ionization processes, and higher energy-density state compared to a single-wire case. In air and water, the single-wire load tends to develop a transverse stratified structure, while PWA is dominated by uneven energy deposition among wires.

Summary: Shaped charges are widely used in various fields, such as military and civilian applications, due to their strong penetration capacities. To enhance the armor-breaking capability, hypervelocity shaped charges (HSCs) have been proposed as a potential solution. Compared with ordinary shaped charges, HSCs can cause severer damage to the target owing to the faster velocity of its jet head.

Summary: This study investigates the use of high-power pulsed discharge to induce fractures for reservoir stimulation. A discharge capsule with a metallic wire inside an Al-powder suspension was designed and tested. The experiments show that there is an optimal concentration of Al-powder suspension to obtain the maximum peak pressure of shock wave. Furthermore, the study finds that the aluminum powder almost does not affect the phase transition of the wire, but it makes the discharge channel more complex and in a higher pressure density state during plasma formation.
