我们一直在研究水下爆炸引起的冲击波传播现象，用于一个强大的食品加工系统。该系统包括一个高压电容器组与间隙开关，水箱，和线炸药。我们利用水槽中的放电对电线爆炸产生的冲击波进行了光学观测。同时，我们测量了冲击压力，并研究了各种电特性对冲击波传播现象的影响。为了获得水下冲击波的各种强度，在各种电压下使用由1.0 mm厚的铝板制成的0.6 mm、1.0 mm和1.4 mm宽的电线。作为示例，使用1.0 mm宽的铝线的爆炸来观察具有1，600 m/s的传播速度的冲击波。我们发现，冲击波的强度可以很好地控制的放电电压和导线的尺寸。
We have been investigating underwater-explosion-induced shockwave-propagation phenomena for use in a robust food-processing system. This system comprises a high-voltage capacitor bank with gap switch, water tank, and wire explosive. We carried-out optical observation of the shockwave generated by a wire explosion using electrical discharge in the water tank. Simultaneously, we measured the shock pressure and investigated the effects of various electrical characteristics upon the shockwave-propagation phenomena. To obtain various strengths of the underwater shockwave, 0.6-, 1.0-, and 1.4-mm-wide wires made from 1.0-mm-thick aluminum plates were used at various voltages. As an example, a shockwave having a propagation velocity of 1,600 m/s was observed using the explosion of the 1.0-mm-wide aluminum wire. We found that the strength of the shockwave could be well-controlled by the discharge voltage and wire size.
