Hydrodynamic density-functional theory for the moving contact-line problem reveals fluid structure and emergence of a spatially distinct pattern
Andreas Nold, Benjamin D. Goddard, David N. Sibley +1
Understanding the nanoscale effects controlling the dynamics of a contact line -- defined as the line formed at the junction of two fluid phases and a solid -- has been a longstand…
The pressure tensor across a liquid-vapour interface
Carlos Braga, Edward Smith, Andreas Nold +2
Inhomogeneous fluids exhibit physical properties that are neither uniform nor isotropic. The pressure tensor is a case in point, key to the mechanical description of the interfacia…
Pseudospectral methods for density functional theory in bounded and unbounded domains
Andreas Nold, Benjamin D. Goddard, Peter Yatsyshin +2
Classical Density Functional Theory (DFT) is a statistical-mechanical framework to analyze fluids, which accounts for nanoscale fluid inhomogeneities and non-local intermolecular i…
Nanoscale fluid structure of liquid-solid-vapour contact lines for a wide range of contact angles
Andreas Nold, David N. Sibley, Benjamin D. Goddard +1
We study the nanoscale behaviour of the density of a simple fluid in the vicinity of an equilibrium contact line for a wide range of Young contact angles between 40 and 135 degrees…
Fluid structure in the immediate vicinity of an equilibrium three-phase contact line and assessment of disjoining pressure models using density functional theory
Andreas Nold, David N. Sibley, Benjamin D. Goddard +1
We examine the nanoscale behavior of an equilibrium three-phase contact line in the presence of long-ranged intermolecular forces by employing a statistical mechanics of fluids app…
Statistical Mechanics of a Thin Film on a Solid Substrate
Andreas Nold
We study the behavior of very thin liquid films wetting homogeneous planar and spherical substrates. In order to describe a simple fluid at very small scales, we employ a classical…
Symmetry Analysis in Linear Hydrodynamic Stability Theory: Classical and New Modes in Linear Shear
Andreas Nold, Martin Oberlack
We present a symmetry classification of the linearised Navier-Stokes equations for a two-dimensional unbounded linear shear flow of an incompressible fluid. The full set of symmetr…
The contact line behaviour of solid-liquid-gas diffuse-interface models
David N. Sibley, Andreas Nold, Nikos Savva +1
A solid-liquid-gas moving contact line is considered through a diffuse-interface model with the classical boundary condition of no-slip at the solid surface. Examination of the asy…
A comparison of slip, disjoining pressure, and interface formation models for contact line motion through asymptotic analysis of thin two-dimensional droplet spreading
David N. Sibley, Andreas Nold, Nikos Savva +1
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…
On the moving contact line singularity: Asymptotics of a diffuse-interface model
David N. Sibley, Andreas Nold, Nikos Savva +1
The behaviour of a solid-liquid-gas system near the three-phase contact line is considered using a diffuse-interface model with no-slip at the solid and where the fluid phase is sp…
Generalized dynamical density functional theory for classical fluids and the significance of inertia and hydrodynamic interactions
Benjamin D. Goddard, Andreas Nold, Nikos Savva +2
We study the dynamics of a colloidal fluid including inertia and hydrodynamic interactions, two effects which strongly influence the non-equilibrium properties of the system. We de…
Wetting on a spherical wall: influence of liquid-gas interfacial properties
Andreas Nold, Alexandr Malijevský, Serafim Kalliadasis
We study the equilibrium of a liquid film on an attractive spherical substrate for an intermolecular interaction model exhibiting both fluid-fluid and fluid-wall long-range forces.…
