Molecular dynamics analysis for the effect of the wettability and the slip on the solid wall surface on bubble growth

open access: yesNihon Kikai Gakkai ronbunshu, 2023
Since the boiling heat transfer is much affected by the nucleation of bubble and its growth, estimation of such process is essential for the accurate prediction of the heat transfer.

Interface Behavior between Two Fluids Vertically Oscillated in a Circular Cylinder under Nonlinear Contact Line Condition

open access: yesJournal of Fluid Science and Technology, 2008
The development of waves on a fluid-fluid interface, excited by a vertical, relative motion of a solid wall enclosing the fluids, is affected significantly by the mobility of the interface on the wall.

Dependency of Contact Angles on Three-Phase Contact Line: A Review

open access: yesColloids and Interfaces, 2021
The wetted area of a sessile droplet on a practical substrate is limited by the three-phase contact line and characterized by contact angle, contact radius and drop height.

Transition in a numerical model of contact line dynamics and forced dewetting [PDF]

open access: yes, 2018
We investigate the transition to a Landau-Levich-Derjaguin film in forced dewetting using a quadtree adaptive solution to the Navier-Stokes equations with surface tension.

Volume and Frequency-Independent Spreading of Droplets Driven by Ultrasonic Surface Vibration

open access: yesFluids, 2020
Many industrial processes depend on the wetting of liquids on various surfaces. Understanding the wetting effects due to ultrasonic vibration could provide a means for changing the behavior of liquids on any surface.

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 role of the microscale contact line dynamics in the wetting behaviour of complex fluids

open access: yesArchives of Mechanics, 2015
The microscale morphology of the liquid-substrate contact line is studied experimentally in two well-known examples of dynamic wetting with complex fluids (namely, drop impact of dilute polymer solutions and spreading of superspreader surfactant ...

Dynamical model for the formation of patterned deposits at receding contact lines [PDF]

open access: yes, 2010
We describe the formation of deposition patterns that are observed in many different experiments where a three-phase contact line of a volatile nanoparticle suspension or polymer solution recedes.

A comparison of slip, disjoining pressure, and interface formation models for contact line motion through asymptotic analysis of thin two-dimensional droplet spreading [PDF]

open access: yes, 2014
The motion of a contact line is examined, and comparisons drawn, for a variety of models proposed in the literature. Pressure and stress behaviours at the contact line are examined in the prototype system of quasistatic spreading of a thin two ...
