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

Bouncing dynamics of droplets on nanopillar-arrayed surfaces: the effect of impact position.
TL;DR: In this article , the impact position of a water droplet on a nanopillar-arrayed surface is investigated, and the effect of impact position on its bouncing dynamics is shown to be highly sensitive to the impact velocity.

A Theoretical Model of Soil Aerosol Generation and Vertical Transport During Rainfall
TL;DR: In this article , the authors proposed a mathematical description on the generation of soil aerosol and measured the production rate of aerosols from laboratory simulations of raindrops impinging on soils to support the assumptions made in their theory.

Droplet deformation by short laser-induced pressure pulses
TL;DR: In this paper, an acoustic analytic model for the pressure, pressure impulse and velocity fields inside a free-falling liquid droplet is developed in the limit of small density fluctuations.

Droplet impingement on a solid surface: Parametrization and asymmetry of dynamic contact angle model
TL;DR: In this paper , the authors proposed a scheme to parameterize a dynamic contact angle (DCA) model and tune its parameters for systems of different levels of wettability to simulate the spreading behavior of droplets on a solid surface.
