摘要 本文介绍了液滴撞击水平表面的实验研究结果。研究了冲击参数对液滴冲击的影响。结果显示了不同液滴韦伯数（范围从 50 到 1080）以及三种液体：水、异丙醇和甘油。使用四种具有特征润湿性（以接触角给出）的表面：光滑玻璃、PVC、蜡和粗糙玻璃。我们详细研究了传播过程中移动接触线的运动学。我们特别感兴趣的是液体对壁的润湿性的影响。据观察，表面润湿性对过程后期液滴的扩散有很大影响。结果以图表的形式呈现，描述了液滴随时间的扩散直径和顶点高度。
Abstract This paper presents the results of an experimental investigation of droplets impacting on horizontal surfaces. The effects of the impact parameters on the droplet impingement are studied. The results are presented for different droplet Weber numbers, ranging from 50 to 1080 and for three liquids: water, isopropanol and glycerin. Four kinds of surfaces were used with characteristic wettability (given in terms of the contact angle): smooth glass, PVC, wax and rough glass. We studied in some detail the kinematics of the moving contact line during the spreading process. Particularly we are interested in the effects of the wettability of the wall by the liquid. The surface wettability has been observed to have a strong influence on the spreading of droplet in the later stages of the process. The results are presented in the form of charts describing the spreading diameter and apex height of droplets in terms of time.
