当沿倾斜的固体表面流下的薄层液体变得不稳定时，可能会出现干燥区域。确定控制液体再湿固体能力的参数，以便重新建立均匀的液膜，具有普遍的工程意义。通过进行Huppert介绍的一组具体实验来研究接触角在再湿过程中所起的作用[(Natural 300,427(1982)])。结果表明，较小的静推进接触角对再湿有促进作用，而较大的静推进接触角则不利于再湿。
When a thin layer of liquid flowing down an inclined solid surface becomes unstable, a dry region may appear. It is of general engineering interest to identify the parameters which control the ability of the liquid to rewet the solid so that a uniform film of liquid can be reestablished. The role played by the contact angle in the rewetting process is investigated by performing a specific set of experiments of the type introduced by Huppert [(Nature 300, 427 (1982)]. It is found that a small static advancing contact angle promotes rewetting, while a large value of the angle does not.
