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

Coalescence of Microscopic Polymeric Drops: Effect of Drop Impact Velocities.
TL;DR: In this paper, the authors employ the direct numerical simulation (DNS) method for probing three-dimensional, axisymmetric coalescence of microscale, power-law-obeying, and shear-thinning polymeric liquid drops of identical sizes impacting a solid, solvophilic substrate with a finite velocity.

Impact behaviors of a millimetric impinging drop on a superheated Al alloy surface
TL;DR: The dynamic Leidenfrost point (at which the film boiling and contact boiling regimes are differentiated) is revealed, which is dependent on the Weber number, and the spreading characteristic is estimated in terms of the maximum spreading diameter.
