对冲击波在毛细管中的传播进行了实验研究。冲击波分别由高功率飞秒激光和毛细管中的高速磁阀产生。与传统的宏观冲击波产生方法不同的是，这些方法可以研究亚毫米到微米尺度的冲击波。实验中的低雷诺数流动使得Mirels[1]和Brouillette[2]提出的向下尺度和边界效应的研究成为可能。标度效应使毛细管内的流动不同于宏观激波管中的流动。实验结果表明，它偏离了经典的激波理论。
Shock wave propagation in a capillary is investigated experimentally. Shock waves are generated by a high-power fs laser or a high-speed magnetic valve in a capillary, respectively. In contrast to those conventional methods of macroscopic shock wave generation which involve a diaphragm, the current methods enable the investigation of shock waves in the submillimeter toward the micrometer scale. The low Reynolds number flows in the experiments enable the study of downscaling and the boundary effects as suggested by Mirels [1] and Brouillette [2]. Scaling effects make the flow in a capillary different from that in a macroscopic shock tube. The experimental results show the deviation from the classical shock theory.
