Droplet motion on chemically heterogeneous substrates with mass transfer. II. Three-dimensional dynamics
Nikos Savva, Danny Groves
We consider a thin droplet that spreads over a flat, horizontal and chemically heterogeneous surface. The droplet is subjected to changes in its volume though a prescribed, arbitra…
Droplet motion on chemically heterogeneous substrates with mass transfer. I. Two-dimensional dynamics
Danny Groves, Nikos Savva
We consider the dynamics of thin two-dimensional viscous droplets on chemically heterogeneous surfaces moving under the combined effects of slip, mass transfer and capillarity. The…
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…
Slip or not slip? A methodical examination of the interface formation model using two-dimensional droplet spreading on a horizontal planar substrate as a prototype system
David N. Sibley, Nikos Savva, Serafim Kalliadasis
We consider the spreading of a thin two-dimensional droplet on a planar substrate as a prototype system to compare the contemporary model for contact line motion based on interface…
Two-dimensional droplet spreading over random topographical substrates
Nikos Savva, Serafim Kalliadasis, Grigorios A. Pavliotis
We examine theoretically the effects of random topographical substrates on the motion of two-dimensional droplets via appropriate statistical approaches. Different random substrate…
