Lubrication Film Generation with Limited Lubricant Supply and Its Tuned Oil Replenishment in a Cylinder-on-Disc Contact

open access: yesLubricants, 2023
Limited lubricant supply (LLS) with tuned dosage is an emerging approach to reduce friction and energy consumption. However, LLS can cause severe starvation when the oil supply is insufficient.

Prediction of Contact and Lubrication Characteristics of Micro-textured Surface Under Thermal Line Contact EHL

open access: yesFrontiers in Mechanical Engineering, 2021
In this study, a method combining numerical surface generation technology and three-dimensional hot-line contact EHL is employed to evaluate the contact characteristics of micro-textured surfaces under high-load line contact.

Mode Bifurcation on Contact Line Dynamics at Oil/Water Interface Depending on the Contact Line Length

open access: yesFrontiers in Chemistry, 2021
The motion of the contact line at the oil/water interface caused by chemical reactions is well known as a typical example of artificial active matter in the field of nonlinear science.

Time-dependent measurements of length and area of the contact line in contact-boiling regime

open access: yes, 2021
During the impact of a liquid droplet on a sufficiently heated surface, bubble nucleation reduces the contact area between the liquid and the solid surface.

Molecular Desorption by a Moving Contact Line

open access: yesPhysical Review Letters, 2021
The interaction of the contact line with topographical or chemical defects at the nanometer scale sets the macroscopic wetting properties of a liquid on a solid substrate. Based on specific atomic force microscopy (AFM) experiments, we demonstrate that molecules physically sorbed on a surface are removed by a dynamic contact line.

A miniature non-circular line gear with pure-rolling contact

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing, 2021
The design of pure-rolling gear has always been a subject of intense research, because in some working conditions, such as dry friction, pure-rolling gear has higher transmission efficiency and less possibility of transmission failure. Non-circular gears

Critical Dynamics of Contact Line Depinning [PDF]

open access: yesMRS Proceedings, 1994
ABSTRACTThe depinning of a contact line is studied as a dynamical critical phenomenon by a functional renormalization group technique. In D = 2 - ∈ “line” dimensions, the roughness exponent is ζ = ∈/3 to all orders in perturbation theory. Thus, ζ = 1/3 for the contact line, equal to the Imry-Ma estimate for equilibrium roughness. The dynamical exponent

The influence of contact line velocity and acceleration on the dynamic contact angle: An experimental study in microgravity [PDF]

open access: yes, 2011
In this study, a novel experimental method by using the short-time microgravity condition created by the drop tower facility is proposed to investigate the dependence of dynamic contact angle on both the velocity and acceleration of contact line.

Is contact-line mobility a material parameter?

open access: yesnpj Microgravity, 2022
Dynamic wetting phenomena are typically described by a constitutive law relating the dynamic contact angle θ to contact-line velocity U C L . The so-called Davis–Hocking model is noteworthy for its simplicity and relates θ to U C L through a contact-line
