Abstract使用矩形激波管,在马赫数分别为M=1.5和1.7的条件下实验研究了气/液界面上(即Atwood数A接近1时)由Richtmyer-Meshkov不稳定性引起的流体混合现象.得到了气/液界面上Richtmyer-Meshkov不稳定性后期流体混合区域宽度随时间的发展呈现出线性关系的结果,即h∝t.比较了不同马赫数和初始扰动下的发展情况,发现当马赫数增加时,同一时间混合区域宽度随之增加,混合区域宽度增长变快;而相比于波长差别不大的弱多模态初始扰动(无人为干扰界面),当界面初始扰动获得随机外界干扰时,界面混合区域具有较大的宽度以及增长速度.并且增加激波马赫数和初始扰动多模态性,流体混合程度更为剧烈
