Abstract We present a comprehensive study of the dispersion of capillary waves with finite amplitude, based on direct numerical simulations. The presented results show an increase of viscous attenuation and, consequently, a smaller frequency of capillary waves with increasing initial wave amplitude. Interestingly, however, the critical wavenumber as well as the wavenumber at which the maximum frequency is observed remain the same for a given two-phase system, irrespective of the wave amplitude… 

Solitary waves on falling liquid films in the inertia-dominated regime

We offer new insights and results on the hydrodynamics of solitary waves on inertia-dominated falling liquid films using a combination of experimental measurements, direct numerical simulations (DNS)

Axisymmetric viscous interfacial oscillations – theory and simulations

We study axisymmetric, free oscillations driven by gravity and surface tension at the interface of two viscous, immiscible, radially unbounded fluids, analytically and numerically. The interface is

We consider dissipation of surface waves on fluids, with a view to its effects on analogue gravity experiments. We begin by reviewing some general properties of wave dissipation, before restricting

Modelling the hydrodynamic effect of abrupt water depth changes on a ship travelling in restricted waters using CFD

ABSTRACT Shallow water studies of ship hydrodynamics typically examine a single, constant underwater canal cross-section at a time. In practice, the underwater cross-sectional area and shape of the

GeoChemFoam: Operator Splitting based time-stepping for efficient Volume-Of-Fluid simulation of capillary-dominated two-phase flow

We present a novel time-stepping method, called Operator Splitting with Capillary Relaxation (OSCAR), for efficient Volume-Of-Fluid simulations of capillary-dominated two-phase flow. OSCAR uses

Comparison of free surface and conservative Allen-Cahn phase field lattice Boltzmann method

This study compares the free surface lattice Boltzmann method (FSLBM) with the conservative Allen-Cahn phase-field lattice Boltzmann method (PFLBM) in their ability to model two-phase flows in which

Universal Stokes’s nanomechanical viscometer

A simple yet universal viscometer is demonstrated, exploiting damping of capillary waves generated electrically and probed optically with sub-nanoscale precision, exploiting Dickinsonian damping mechanism for picomechanical optofluidics.

Frequency dispersion of small-amplitude capillary waves in viscous fluids.

The presented results suggest that the widely adopted hydrodynamic theory for damped capillary waves does not accurately predict the dispersion when viscous damping is significant, and an alternative definition of the damping rate is presented, which provides consistent accuracy in the underdamped regime.

Direct numerical simulations of capillary wave turbulence.

This work presents direct numerical simulations of capillary wave turbulence solving the full three-dimensional Navier-Stokes equations of a two-phase flow, confirming the validity of the weak turbulence approach to quantify out-of equilibrium wave statistics.

An exact solution is found in a fairly simple form for two-dimensional progressive waves of arbitrary amplitude on a fluid of unlimited depth, when only surface tension and not gravity is taken into

Viscous effects on small‐amplitude surface waves

The transient behavior of small‐amplitude standing waves on the plane surface of an infinitely deep viscous liquid is investigated. An integro‐differential equation of motion for the free surface is

Viscosity effect on capillary waves at liquid interfaces

We discuss the viscosity damping effect on capillary waves in a binary-liquid system, using the linearized Navier-Stokes equation. The damping correction for the dispersion relation depends on the

Observation of gravity-capillary wave turbulence.

The probability density functions of the turbulent wave height are found to be asymmetric and thus non-Gaussian and the scaling of those spectra with the mean energy flux is found in disagreement with weak turbulence theory for both regimes.

Exact large amplitude capillary waves on sheets of fluid

We generalize Crapper's exact solution for capillary waves on fluid of infinite depth. We find two finite-depth solutions involving elliptic functions. We show they can also be interpreted as large
