在微秒级时间尺度上对铜丝进行水下电爆炸，产生水下冲击波。实验结果表明，再冲击后水流的径向密度分布包含若干振荡，在背光条纹图像和激光阴影图中观察到间距为0.1mm的层。这种现象是由于爆炸产物（EP）的部分再加热的内部再燃电弧，这刺激了压缩波在EP中径向来回传播。模拟被用来支持内部故障的情况下，并证明在EP-水界面处的压缩波的每个反射发射到水中的弱冲击，形成多层结构。当周围的金属蒸汽由于电弧的辐射和热传导而电离时，高传导性等离子体通道继续径向延伸并发射主压缩波，当功率注入时，该压缩波淹没多层膜。
Underwater electrical explosions of Cu wires were carried out on a microsecond time scale to produce underwater shock waves. Experimental results show that the radial density distribution of the water flow after restrike contains several oscillations, observed as ∼1 mm-spaced layers in the backlit streak images and laser shadowgraphs. The phenomenon is attributed to the partial reheating of the exploding product (EP) by an interior restrike arc, which stimulates a compression wave propagating back and forth radially in the EP. Simulations are used to support the interior breakdown scenario and to demonstrate that each reflection of the compression wave at the EP–water interface launches a weak shock into the water, forming a multilayer structure. As the surrounding metallic vapor is ionized due to radiation and thermal conduction from the arc, the highly conductive plasma channel continues to extend radially and launches the main compression wave, which drowns out the multilayers when the power injection ...
