Description
This paper presents the results of experimental investigation of droplets impact on horizontal surfaces. The effects of the impact parameters on the droplet impingement is 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), the smooth glass, PVC, wax and rough glass. We studied in some detail the kinematics of the moving contact line during of 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 chars describing the spreading diameter and apex height of droplets in terms of time.
