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.

Aerodynamic effect of icing/rain impacts on super-hydrophobic surfaces

TL;DR: In this paper, the authors explored the possibility of using a fast and cheap technology of R2R-EC to enable the fabrication of nanostructures on polymer foils of sizes ranging from 50 nanometers and up to 100 micrometers with the aim of improving the ice-cleaning and water-repellent properties of the coating.

Effect of Surface Roughness on Hydrodynamic Characteristics of an Impinging Droplet

TL;DR: The influence of surface roughness and impact energy on the hydrodynamic behavior of water droplets impinging upon dry and rigid surfaces of known roughness has been investigated experimentally and a correlation for the maximum spreading diameter in terms of the nondimensional parameter (The authors/Oh) and surface Roughness ratio (Ra/do) was derived.

Interplay of substrate inclination and wettability on droplet impact dynamics

TL;DR: In this paper, the role of surface wettability and inclination on the post impact dynamics of droplets was investigated on inclined SH surfaces, where different features like arrest of secondary droplet formation, reduced pinch off at the contact line and inclination dependent elongation mechanism were observed.

Two-Pronged Jet Formation Caused by Droplet Impact on Anisotropic Superhydrophobic Surfaces

TL;DR: In this paper, a liquid droplet impacts a superhydrophobic surface with anisotropic surface patterning in the form of alternating ribs and cavities, the rebounding droplet may exhibit a unique two-pronged jet emission.
