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.

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.

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

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.

Dissipation in dynamics of a moving contact line [PDF]

open access: yesPhysical Review E, 2001
The dynamics of the deformations of a moving contact line is studied assuming two different dissipation mechanisms. It is shown that the characteristic relaxation time for a deformation of wavelength $2π/|k|$ of a contact line moving with velocity $v$ is given as $τ^{-1}(k)=c(v) |k|$.

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 ...

Catenoid Stability with a Free Contact Line [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2015
Contact-drop dispensing is central to many small-scale applications, such as direct-scanning probe lithography and micromachined fountain-pen techniques. Accurate and controllable dispensing required for nanometer-resolved surface patterning hinges on the stability and breakup of liquid bridges.
