Multi-dimensional modeling of thin liquid films and spray-wall interactions resulting from impinging sprays
TLDR
In this article, a multi-dimensional, fuel film model is proposed to simulate thin fuel film flow on solid surfaces of arbitrary configuration, which is achieved by solving the continuity, momentum, and energy equations for the two-dimensional film that flows over a three-dimensional surface.About:

Spray impact: Rim transverse instability initiating fingering and splash, and description of a secondary spray
TL;DR: In this article, a semi-empirical model for the secondary spray has been proposed and validated using a numerical simulation of spray transport based on an Euler-Lagrange approach.

Dynamic contact angle effects onto the maximum drop impact spreading on solid surfaces
TL;DR: In this paper, a high speed video camera was used to follow in time the drop spreading, and it allows us to determine precisely the expansion of the drop and the profile of the free surface at the contact line.

Collision phenomena in liquids and solids
TL;DR: A comprehensive account of the physical foundations of collision and impact phenomena and their applications in a multitude of engineering disciplines can be found in this paper, including theoretical and applied mechanics, physics and applied mathematics, materials science, aerospace, mechanical and chemical engineering, and terminal ballistics.

Heat transfer characteristics of a supercritical fluid flow in a vertical pipe
TL;DR: In this paper, the similarity of heat transfer of supercritical fluid flow in vertical pipes at different diameters was explored by performing comparative experiments. But the authors did not consider the effect of the diameter of the pipe on the heat transfer.

An Experimental Evaluation of an Atomization-Based Cutting Fluid Application System for Micromachining
TL;DR: In this article, an atomization-based cutting fluid application system is developed for micro-end milling, which is designed to ensure spreading of the droplets on the workpiece surface based on the analysis of atomized droplet impingement dynamics.

Phenomena of liquid drop impact on solid and liquid surfaces
TL;DR: The fluid dynamic phenomena of liquid drop impact are described and reviewed in this article, and specific conditions under which the above phenomena did occur in experiments are analyzed and the characteristics of drop impact phenomena are described in detail.
Journal ArticleDOI
Droplet-wall collisions: Experimental studies of the deformation and breakup process
TL;DR: In this article, a model of the deposition-splashing boundary in terms of Reynolds number and Ohnesorge number is presented, which is only achieved if the normal velocity component of the impinging droplets is used in these dimensionless numbers.

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.

An experimental investigation of fluid flow resulting from the impact of a water drop with an unyielding dry surface
C. D. Stow,M. G. Hadfield +1 more
TL;DR: In this paper, it is shown that the primary influence of the surface roughness parameter R a is the determination of the condition for the ejection of secondary droplets by the excitation of an instability in the developing watersheet; provided R a ≪ R, it is possible to evaluate the condition to a high degree of accuracy, and for R a = 0.84 μm it is found to be α4/3 RV 1.4.

TL;DR: In this article, a computer model was used to study the impingement of sprays on walls, accounting for the effects of drop breakup, drop collision and coalescence, and the effect of drops on the gas turbulence.
