对液膜绕水平圆柱流动的特性进行了实验和理论研究。在膜表面出现有峰线指向流动方向的驻波。波长由膜表面的力平衡和离心力的影响从理论上得到。计算的波长与三种测试液体的实验测量值一致。当膜雷诺数大于500时，粘性对波动的影响可以忽略不计。
An experimental and theoretical study was conducted to investigate the characteristics of liquid film flowing around a horizontal circular cylinder. The standing wave with a peak line pointing to the flow direction appears on the film surface. The wave length was obtained theoretically from the force balance on the film surface including the effect of centrifugal force. The calculated wave lengths agree with those measured experimentally for three kinds of test liquids. When the film Reynolds number increases larger than 500, the viscous effect on the wave motion can be neglected.
