In this article, the impact of a liquid drop of low viscosity on a super-hydrophobic surface was studied. But the authors focused on the effect of the drop on the spread of the liquid on the surface.Abstract:
We first study the impact of a liquid drop of low viscosity on a super-hydrophobic surface. Denoting the drop size and speed as are the liquid density and surface tension). This law is also observed to hold on partially wettable surfaces, provided that liquids of low viscosity (such as water) are used. The law is interpreted as resulting from the effective acceleration experienced by the drop during its impact. Viscous drops are also analysed, allowing us to propose a criterion for predicting if the spreading is limited by capillarity, or by viscosity.read more

Droplet impact on a hydrophobic surface integrated with electrowetting technique
TL;DR: In this article , the effect of electrowetting on the droplet impact on a hydrophobic surface can be controlled by varying the wettability of the surface, and a numerical technique with a dynamic contact model is developed to track the movement of the three-phase contact line.

Water drop impacts on regular micropillar arrays: Asymmetric spreading
TL;DR: In this article , high-speed imaging of droplet shapes following impact was used to record and analyze asymmetries as drop spreading reaches its maximum extent, with results varying (often non-monotonically) from symmetric spreading to many fingers.
