TLDR
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

Impact of Viscous Droplets on Superamphiphobic Surfaces
TL;DR: The critical impact velocity, above which droplets can rebound from the superamphiphobic surface, was found to linearly increase with the liquid viscosity, and it was shown that the maximum spreading factor increases with Weber number or Reynolds number but decreases with theLiquid viscosities.

Bloodstain Pattern Analysis: implementation of a fluid dynamic model for position determination of victims
TL;DR: This study determines how accurately the location of the origin can be estimated when including gravity and drag into the trajectory reconstruction and enables investigators to determine if the victim was sitting or standing, or it might be possible to connect wounds on the body to specific patterns, which is important for crime scene reconstruction.

Imparting Icephobicity with Substrate Flexibility
TL;DR: In this paper, the collaborative effect of substrate flexibility and surface micro/nanotexture on enhancing both icephobicity and the repellency of viscous droplets was investigated.
