Lift at low Reynolds number

L Bureau, G Coupier, T Salez - The European Physical Journal E, 2023 - Springer
Lift forces are widespread in hydrodynamics. These are typically observed for big and fast
objects and are often associated with a combination of fluid inertia (ie large Reynolds …

Marangoni flow at droplet interfaces: Three-dimensional solution and applications

M Schmitt, H Stark - Physics of Fluids, 2016 - pubs.aip.org
The Marangoni effect refers to fluid flow induced by a gradient in surface tension at a fluid-
fluid interface. We determine the full three-dimensional Marangoni flow generated by a non …

Uniform electric-field-induced lateral migration of a sedimenting drop

A Bandopadhyay, S Mandal, NK Kishore… - Journal of Fluid …, 2016 - cambridge.org
We investigate the motion of a sedimenting drop in the presence of an electric field in an
arbitrary direction, otherwise uniform, in the limit of small interface deformation and low …

Inertial migration of deformable droplets in a microchannel

X Chen, C Xue, L Zhang, G Hu, X Jiang, J Sun - Physics of Fluids, 2014 - pubs.aip.org
The microfluidic inertial effect is an effective way of focusing and sorting droplets suspended

Viscous Marangoni migration of a drop in a Poiseuille flow at low surface Péclet numbers

OS Pak, J Feng, HA Stone - Journal of fluid mechanics, 2014 - cambridge.org
The motion of a spherical drop with a bulk-insoluble surfactant immersed in a background
flow in the limits of low surface Péclet number and low Reynolds number is investigated. We …

The effect of uniform electric field on the cross-stream migration of a drop in plane Poiseuille flow

S Mandal, A Bandopadhyay… - Journal of Fluid …, 2016 - cambridge.org
The effect of a uniform electric field on the motion of a drop in an unbounded plane
Poiseuille flow is studied analytically. The drop and suspending media are considered to be …

Effect of surfactant on motion and deformation of compound droplets in arbitrary unbounded Stokes flows

S Mandal, U Ghosh, S Chakraborty - Journal of Fluid Mechanics, 2016 - cambridge.org
This study deals with the motion and deformation of a compound drop system, subject to
arbitrary but Stokesian far-field flow conditions, in the presence of bulk-insoluble surfactants …

Interfacial effects on droplet dynamics in Poiseuille flow

JT Schwalbe, FR Phelan Jr, PM Vlahovska, SD Hudson - Soft Matter, 2011 - pubs.rsc.org
Many properties of emulsions arise from interfacial rheology, but a theoretical understanding
of the effect of interfacial viscosities on droplet dynamics is lacking. Here we report such a …

Electrohydrodynamic interaction between droplet pairs in a confined shear flow

S Santra, D Sen, S Das, S Chakraborty - Physics of Fluids, 2019 - pubs.aip.org
This study deals with electrohydrodynamic interactions between two deformable droplets in
a confined shear flow. We have investigated the effect of the channel confinement and the …
