摘要：

Underwater electrical wire explosion driven by a high-power electric pulse is accompanied by physical effects such as shock wave, plasma and strong light radiation. Therefore, it has achieved remarkable results in the underwater explosion simulation and the exploition of unconventional oil and gas. Due to the skin effect and the limited electrical insulation of the equipment, it is often impossible to obtain the required shock wave by increasing the stored energy and load quality without limitation. In this paper, the underwater electrical explosion of copper wire is used to ignite the aluminum powder suspensions with particle sizes of 10 μm and 1 μm to find the mechanism of detonation of aluminum powder suspension to enhance shock wave. The details of space-time evolution of aluminum powder suspension ignited by the electrical explosion are obtained through the diagnosis of electrical physical parameters and high-speed backlight images. The discharge characteristics and ignition mechanism of aluminum powder suspension under electric-hydraulic breakdown and electrical explosion are studied, and the relationship between the stored energy and shock wave is established. It is found that the ignition of aluminum powder suspension by electrical wire explosion is a result of the joint action of near-field shock wave, plasma and strong light radiation, and then the continuously combusting aluminum powder injects energy into the surrounding compressed water layer, which enhances the amplitude, positive action time and impulse of shock wave. © 2023 China Ordnance Society.
