TLDR
In this article, the impact of a single drop on a liquid film is studied numerically by solving the Navier-Stokes equations for incompressible fluids in three dimensions, and the extension dynamics of the splashing lamella is analyzed and compared with theoretical results from the literature.About:

Drop Impact Dynamics: Splashing, Spreading, Receding, Bouncing ...
TL;DR: In this article, a review deals with drop impacts on thin liquid layers and dry surfaces, referred to as splashing, and their propagation is discussed in detail, as well as some additional kindred, albeit nonsplashing, phenomena like drop spreading and deposition, receding (recoil), jetting, fingering, and rebound.

Dynamic contact angle of spreading droplets: Experiments and simulations
TL;DR: In this article, a single drop impact onto a dry, partially wettable substrate and its numerical simulation was investigated. And the authors showed that existing empirical models for the dynamic contact angle (e.g., Hoffman-Voinov-Tanner law) do not predict well the change of dynamic contact angles, especially at high capillary numbers.

Advances and challenges in explaining fuel spray impingement: How much of single droplet impact research is useful?
TL;DR: In this paper, a critical review of the literature on spray-wall impact relevant to IC engines is presented, in an attempt to address the rationale of describing spraywall interactions based on the knowledge of single droplet impacts.

Modeling the splash of a droplet impacting a solid surface
TL;DR: In this article, a numerical model is used to simulate the fingering and splashing of a droplet impacting a solid surface, and a methodology is presented for perturbing the velocity of fluid near the solid surface at a time shortly after impact.

A conservative phase field method for solving incompressible two-phase flows
Pao-Hsiung Chiu,Yan-Ting Lin +1 more
TL;DR: The present method can preserve the total mass as the Cahn-Hilliard equation, but the calculation and implementation are much simpler than that and the satisfactions of mass conservations are guaranteed.

Volume of fluid (VOF) method for the dynamics of free boundaries
C.W Hirt,B. D. Nichols +1 more
TL;DR: In this paper, the concept of a fractional volume of fluid (VOF) has been used to approximate free boundaries in finite-difference numerical simulations, which is shown to be more flexible and efficient than other methods for treating complicated free boundary configurations.

Modelling Merging and Fragmentation in Multiphase Flows with SURFER
TL;DR: In this article, the Navier-Stokes equation is solved using staggered finite differences on a MAC grid and a split-explicit time differencing scheme, while incompressibility is enforced using an iterative multigrid Poisson solver.

Impact of drops on solid surfaces : self-similar capillary waves, and splashing as a new type of kinematic discontinuity
Alexander L. Yarin,D. A. Weiss +1 more
TL;DR: In this paper, the impact of drops impinging one by one on a solid surface is studied experimentally and theoretically, and it is shown that the splashing threshold corresponds to the onset of a velocity discontinuity propagating over the liquid layer on the wall.
Journal ArticleDOI
The impact of a single drop on a wetted solid surface
TL;DR: In this article, the impact of millimetric drops on a thin liquid film was studied to understand the mechanism of secondary atomisation of sprays colliding on a wetted, cold, solid surface.
