Abstract
The processes of different droplets impacting the solid surface are recorded using a high-speed digital came and the effects of the impact parameters on the droplet impact are studied. The results show that the viscosity of droplet plays a decisive role in spreading process, and surface tension has a leading influence on recoiling process. These two factors jointly determine the oscillation characteristics. The maximum spread factor increases with impact velocity increasing, however, the time from the beginning to achieve the maximum spreading factor shows different variation rules due to surface tension.
