films, drops, and bubbles require detailed understanding of interfacial phenomena and …

Stability of constrained capillary surfaces

JB Bostwick, PH Steen - Annual Review of Fluid Mechanics, 2015 - annualreviews.org
A capillary surface is an interface between two fluids whose shape is determined primarily
by surface tension. Sessile drops, liquid bridges, rivulets, and liquid drops on fibers are all …

Solutions for modelling moving heat sources in a semi-infinite medium and applications to laser material processing

M Van Elsen, M Baelmans, P Mercelis… - International Journal of …, 2007 - Elsevier
This study describes the analytical and numerical solution of the heat conduction equation
for a localised moving heat source of any type for use in laser material processing, as …

Fingering phenomena for driven coating films

MH Eres, LW Schwartz, RV Roy - Physics of Fluids, 2000 - pubs.aip.org
A theoretical and numerical model is formulated to describe the instability and the long-time
evolution of both gravity-driven and surface-shear-stress-driven thin coating films. A single …

Morphology of liquid microstructures on chemically patterned surfaces

AA Darhuber, SM Troian, SM Miller… - Journal of Applied …, 2000 - pubs.aip.org
We study the equilibrium conformations of liquid microstructures on flat but chemically
heterogeneous substrates using energy minimization computations. The surface patterns …

Bioinspired Anti‐Plateau–Rayleigh‐Instability on Dual Parallel Fibers

P Wang, J Zhou, B Xu, C Lu, Q Meng… - Advanced …, 2020 - Wiley Online Library
Abstract The Plateau–Rayleigh instability (PRI) is a well‐known phenomenon where a liquid
column always breaks up into droplets to achieve the minimization of surface energy. It …

On the breakup of fluid rivulets

JA Diez, AG González, L Kondic - Physics of Fluids, 2009 - pubs.aip.org
We study the stability of rivulets on horizontal substrates. The implemented model includes
the effects of capillarity, fluid-solid interaction, and gravity if appropriate, within the …

On the shapes of droplets that are sliding on a vertical wall

LW Schwartz, D Roux, JJ Cooper-White - Physica D: Nonlinear Phenomena, 2005 - Elsevier
This paper presents a straightforward theoretical model for the slow motion of a viscous
liquid drop on an inclined or vertical wall. The model simulates three-dimensional unsteady …

Static rivulet instabilities: varicose and sinuous modes

JB Bostwick, PH Steen - Journal of Fluid Mechanics, 2018 - cambridge.org
A static rivulet is subject to disturbances in shape, velocity and pressure fields. Disturbances
to interfacial shape accommodate a contact line that is either (i) fixed (pinned) or (ii) fully …

Meandering rivulets on a plane: a simple balance between inertia and capillarity

N Le Grand-Piteira, A Daerr, L Limat - Physical review letters, 2006 - APS
Experiments on streams of water flowing down a rigid substrate have been performed for
various plate inclinations and flow rates, and we focused on the regime of stationary …
