我们研制了一个直径为1mm的小型激波管，它具有一个无阻尼的驱动部分。该实验是通过使用我们的小型激波管，其中的冲击波的传播速度的测量与一个专门设计的激光干涉仪在几个压力条件下。氦气和二氧化碳分别用作驱动气体和测试气体。结果表明，我们在直径为1mm的激波管中成功地观测到了弱激波。在弱激波区还观察到完全或部分分散的激波，这归因于CO2振动能的激发。
We have developed a small scale shock tube of 1mm diameter which has a diaphragm-less driver section. The experiment is performed by using our small scale shock tube, where the propagation velocities of the shock waves are measured with a specially designed laser interferometer under several pressure conditions. Helium and CO2 are used as the driver and test gas, respectively. As the results show, we have succeeded in observing weak shock waves in a shock tube of 1mm diameter. The fully or partly dispersed shock waves, which are attributed to the exitation of the vibrational energy of CO2, are also observed at the weak shock region.
