| 摘 要： | 利用激波管对激波诱导气流与液幕、液柱的相互作用进行了实验研究。通过比较发现，这种相互作用下的液体块变形破碎过程与以往对于液滴进行的研究结果很不相同。当激波与液幕相互作用时，阴影照片和直接照相都表明，液幕的变形破碎行为有很强的三维性，较之液滴的变形破坏机理更为复杂，并且在局部区域，初始时刻液幕破碎抛撒的速度相较激波诱导气流速度为快，本文应用一维变截面激波管理论对这一现象进行了理论分析。

| Abstract: | The interaction between shock induced airflow and a freely falling liquid sheet is investigated by using a shock tube. It is found that the deformation, breaking and atomization process of the liquid in this case is quite different from what was found in the previous investigation for liquid droplets acted by shock waves. The phenomenon is analyzed by using a theory for shock tubes with varying sections. |

| Keywords: | shock tube Shock induced airflow breakup of liquid drops |
