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.

A Machine Learning Approach for Predicting the Maximum Spreading Factor of Droplets upon Impact on Surfaces with Various Wettabilities

TL;DR: This work proposes a data-driven approach for estimating the maximum spreading factor using supervised machine learning (ML) algorithms such as linear regression, decision tree, random forest, and gradient boosting, and finds the gradient boosting regression model to be the best-performing model.

Formation of vase-shaped drops

TL;DR: The evolution of the geometrical features of these so-called ''vase-shaped droplets'' is reported and discussed in this article, where the authors describe how a water droplet is highly reshaped to form truncated cones that eventually collapse.

Oblique impacts of water nanodroplets on superhydrophobic surfaces: A molecular dynamics study

TL;DR: In this paper , the impact dynamics of water nanodroplets are investigated via MD simulations, aiming to examine scale effects during nanodron oblique impact, and the MD results show that the significant interface slide can be observed at the nanoscale.
