摘　　要：设计与搭建了大尺寸水膜稳定性实验台,并进行竖直平板上降水膜表面波波动特性实验研究。实验中水膜雷诺数Re的范围为20～1 200。借助电容式水膜测厚仪和高速摄像仪对水膜表面波形态、波幅、波速和波频等过程参数进行测量与分析。实验结果表明:中低水膜Re条件下孤波振幅、弧波波速分别与水膜Re成正比;孤波频率与水膜Re成弱相关性,入口扰动条件与初始轮廓对孤波频率的影响远大于水膜Re的影响。An experiment on surface-wave wave characteristics of falling water film of vertical plate was completed by means of large-scale water film stabilities experiment rig.Surface wave shape pattern,amplitude,speed and frequency were measured and analyzed with capacitance measuring instrument of thin-film thickness and high-speed video camera.Experimental result indicates that solitary wave amplitude and speed are directly proportional to water film Re,respectively.While solitary wave frequency has been suffered much more affect by inlet disturbance and initial contour of water film than water film Re,and has weak dependence with water film Re.
