On the flow of a thin liquid film over a rough rotating disk
TLDR
In this paper, the depletion of thin viscous films due to centrifugation was studied and the depletion histories of the film were given for cases involving regular patterns of surface asperities.Abstract:
This study addresses the depletion of thin liquid films due to centrifugation. Equations describing the flow of a thin viscous film over a rough rotating disk are solved by either an analytical or numerical method. Depletion histories of the film are given for cases involving regular patterns of surface asperities. It is found that surface roughness markedly enhances the retention of a thin liquid film on a rotating disk. Moreover, different topographic structures of the surface roughness lead to different asymptotic limits of liquid retention.read more

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.

TL;DR: In this paper, a commercial TiO2-based catalyst in the form of composite ceramic balls was used as the immobilized photocatalyst on the rotating disk, and LiCl tracer studies conducted at different disk angular velocities, ranging from 20 to 5 rpm, proved that the mixing in the RDPR is close to that of an ideal CSTR.

Experimental study of substrate roughness and surfactant effects on the Landau-Levich law
TL;DR: In this paper, the authors present an experimental study of deviations from the classical Landau-Levich law in the problem of dip coating, showing that film thinning occurs due to the nature of the liquid-gas and liquid-solid interfaces.

Spin coating over topography
L. M. Peurrung,David B. Graves +1 more
TL;DR: In this paper, a model for predicting film thickness profiles around topographical features during spin coating is presented, which is applicable to features of arbitrary geometry in the two lateral dimensions and can be used to study the planarization of real device structures.

Contact of Nominally Flat Surfaces
TL;DR: In this article, the authors proposed a new theory of elastic contact, which is more closely related to real surfaces than earlier theories, and showed how the contact deformation depends on the topography of the surface, and established the criterion for distinguishing surfaces which touch elastically from those which touch plastically.
The properties of random surfaces of significance in their contact.
TL;DR: In this paper, the waveform of a random signal is used as a representation of the profile of a surface, which is completely defined by two parameters, a height distribution and an auto-correlation function.
