Underwater electrical explosion of wire and wire array

课程简介：本课程旨在建立电爆炸的概念，并介绍电爆炸在冲击物理和爆炸模拟中的一些应用。爆炸与金属的液气相变密切相关。相变可以在纳秒内完成。对于爆炸效应的研究，电爆炸提供了一种安全、方便、纯粹的实验室爆炸源，而不需要额外考虑化学反应。此外，这种系统的能量释放功率足够高，可以支持SWs和射流非线性特性的研究。

The course aims to establish the concept of electrical explosion and introduce some application in shock physics and explosion simulations. The explosion is closely related to the liquid-vapor phase transition of the metal. Recent molecular dynamic simulation suggested the phase transition could be finished in a nanosecond. For the research of explosion effects, the electrical explosion provides a safe, convenient, and pure laboratory explosion source, without the extra consideration of chemical reactions. In addition, the energy release power of such system is sufficiently high to support the study of non-linear properties of SWs and jets.
