Effect of Paper Surface Properties on Coated Paper Wettability with Different Fountain Solutions

open access: yesBioResources, 2014
Wetting of coated papers by isopropyl alcohol (IPA)-based fountain solutions or surfactant solutions was studied in this paper. Additionally, the effect of paper surface properties on wetting was analyzed.

Comparison between numerical models for the simulation of moving contact lines [PDF]

open access: yes, 2015
The aim of this study is to discus different numerically models for the simulation of moving contact lines in the context of a Volume of Fluid–Continuum Surface Force (VoF–CSF) method. We focus on the particular situation of spreading drops.

Discrete Element Method for Simulation and Calibration of Cotton Stalk Contact Parameters

open access: yesBioResources, 2022
To improve the accuracy of the discrete element research, physical and simulation experiments were used to calibrate the cotton stalk contact parameters. Based on the stalk-stalk and stalk-steel contact mechanics, the parameters were measured in physical

Relaxation of a dewetting contact line Part 1: A full-scale hydrodynamic calculation

open access: yes, 2007
The relaxation of a dewetting contact line is investigated theoretically in the so-called "Landau-Levich" geometry in which a vertical solid plate is withdrawn from a bath of partially wetting liquid.

A Variational Approach to Contact Angle Saturation and Contact Line Instability in Static Electrowetting [PDF]

open access: yesThe Quarterly Journal of Mechanics and Applied Mathematics, 2009
Drops of a conducting fluid in electrowetting devices tend to spread when a difference of potential V o is set between the drop and an electrode external to it. The classical Lippmann theory predicts unlimited spreading, with a decrease of the contact angle between drop and solid substrate, as one increases V 0 .

Preparation of superhydrophobic paper mulch and study on its anti-UV performance

open access: yesJournal of Saudi Chemical Society, 2021
In order to improve the shortcomings of paper mulch, such as the low water resistance and weather fastness in practical application, the paper mulch with a superhydrophobic structure was prepared by depositing zinc oxide layer and silicon dioxide layer ...

A mesoscopic model for microscale hydrodynamics and interfacial phenomena: Slip, films, and contact angle hysteresis

open access: yes, 2012
We present a model based on the lattice Boltzmann equation that is suitable for the simulation of dynamic wetting. The model is capable of exhibiting fundamental interfacial phenomena such as weak adsorption of fluid on the solid substrate and the ...

Influence and Correction of Refraction Phenomenon in Liquid Contact Angle Measurement in Capillary Tube

open access: yesColloids and Interfaces
By using clear vapor–liquid interface line images of the liquid inside the capillary, the measurement coordinate points of the vapor–liquid interface line were measured. A new method for measuring liquid contact angle has been proposed, which was used to
