Slip-enhanced Rayleigh-Plateau instability of a liquid film on a fibre

Chengxi Zhao et al.

Summary: Boundary conditions at the liquid-solid interface play a crucial role in the dynamics of a liquid film on a fiber. This study develops a theoretical framework based on axisymmetric Stokes equations to investigate the influence of liquid-solid slip on the Rayleigh-Plateau instability of a cylindrical film. The new model reveals that the growth rate of perturbations is overestimated by the classical lubrication model and predicts a slip-dependent dominant wavelength, leading to larger drops on a more slippery fiber. The findings are validated through direct numerical simulations and agree with experimental results.

Thermal capillary waves on bounded nanoscale thin films

Jingbang Liu et al.

Summary: The influence of boundary conditions on the fluctuation of a nanoscale thin film's free surface is studied using stochastic thin-film equations. Linear stability analysis provides the wave eigenmodes, and thermal-capillary-wave theory predicts the wave fluctuation amplitudes. Molecular dynamics simulations validate the theoretical predictions, and a Langevin diffusion model is proposed to explain the oscillations of the contact lines.

Observation of Interfacial Instability of an Ultrathin Water Film

Yoko Tomo et al.

Summary: We observed the instability of a few-nanometer-thick water film encapsulated inside a graphene nanoscroll using transmission electron microscopy. The film formed ripples with a smaller distance than predicted by the classical theory, which can be explained by the van der Waals interactions between the water film and graphene layers. This provides important insights into the behavior of liquid under nanoscale confinement and in nanofluidic systems.

Fluctuation-driven dynamics in nanoscale thin-film flows: Physical insights from numerical investigations

Chengxi Zhao et al.

Summary: The article presents a numerical scheme based on fluctuating hydrodynamics to capture the effects of thermal fluctuations on nanoscale flows. A stochastic lubrication equation is solved on nonuniform adaptive grids to study various nanoscale thin-film flows. The accuracy of the numerical method is verified through comparison with theoretical results. The study reveals that thermal fluctuations slow down the droplet coalescence process and disjoining pressure dominates thin-film rupture in the considered regime.

Influence of thermal fluctuations on nanoscale free-surface flows: A many-body dissipative particle dynamics study

Chengxi Zhao et al.

Summary: In this study, the influence of thermal fluctuations on nanoscale free-surface flows was investigated using the mDPD method. After performing enough independent simulations to obtain convincing ensemble-averaged results, it was demonstrated that mDPD shows good consistency with theories derived from the Landau-Lifshitz Navier-Stokes equations and is more efficient than traditional molecular dynamics (MD) in capturing fluctuating hydrodynamics in nanoscale free-surface flows.

Thermal capillary wave growth and surface roughening of nanoscale liquid films

Y. Zhang et al.

Summary: This study proposed a Langevin model to capture the transient dynamics of surface waves of liquid films, highlighting the surface roughening process of planar films and the unbounded spectrum of annular films due to Rayleigh-Plateau instability. The research also found scaling relations and universality class for surface roughening of planar films.

Relaxation of Thermal Capillary Waves for Nanoscale Liquid Films on Anisotropic-Slip Substrates

Yixin Zhang et al.

Summary: The relaxation dynamics of thermal capillary waves for nanoscale liquid films on anisotropic-slip substrates were studied using molecular dynamics simulations and a Langevin model. The anisotropy of slip on substrates affects the decay rate of wave correlations and the time correlations of waves on anisotropic-slip substrates depend on wave direction. Through the proposed Langevin equation, experimentally verifiable predictions can be made.

Modification of the Fluctuation Dynamics of Ultrathin Wetting Films

C. Clavaud et al.

Summary: This study reports on the impact of intermolecular forces on the fluctuations of supported liquid films, demonstrating that these forces have a strong influence on the dynamics of the film interface at lower frequencies. Experimental data spanning three frequency decades align well with theoretical predictions considering van der Waals forces, highlighting the significance of intermolecular forces on thermal fluctuations in nanoscale confined fluids.
