Fluid-elastic interactions near contact at low reynolds number

B Rallabandi - Annual Review of Fluid Mechanics, 2024 - annualreviews.org
Interactions between fluid flow and elastic structures are important in many naturally
occurring and engineered systems. This review collects and organizes recent theoretical …

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 …

The reciprocal theorem in fluid dynamics and transport phenomena

H Masoud, HA Stone - Journal of Fluid Mechanics, 2019 - cambridge.org
In the study of fluid dynamics and transport phenomena, key quantities of interest are often
the force and torque on objects and total rate of heat/mass transfer from them …

Regimes of soft lubrication

MH Essink, A Pandey, S Karpitschka… - Journal of fluid …, 2021 - cambridge.org
Elastohydrodynamic lubrication, or simply soft lubrication, refers to the motion of deformable
objects near a boundary lubricated by a fluid, and is one of the key physical mechanisms to …

Effect of fluid viscoelasticity, shear stress, and interface tension on the lift force in lubricated contacts

S Hu, F Meng - The Journal of Chemical Physics, 2023 - pubs.aip.org
We consider a cylinder immersed in viscous fluid moving near a flat substrate covered by an
incompressible viscoelastic fluid layer, and study the effect of the fluid viscoelasticity on the …

Elastohydrodynamic lift at a soft wall

HS Davies, D Débarre, N El Amri, C Verdier… - Physical review …, 2018 - APS
We study experimentally the motion of nondeformable microbeads in a linear shear flow
close to a wall bearing a thin and soft polymer layer. Combining microfluidics and 3D optical …

Soft-lubrication interactions between a rigid sphere and an elastic wall

V Bertin, Y Amarouchene, E Raphaël… - Journal of fluid …, 2022 - cambridge.org
The motion of an object within a viscous fluid and in the vicinity of a soft surface induces a
hydrodynamic stress field that deforms the latter, thus modifying the boundary conditions of …

Lift forces on three-dimensional elastic and viscoelastic lubricated contacts

A Kargar-Estahbanati, B Rallabandi - Physical Review Fluids, 2021 - APS
When an object suspended in fluid moves past a soft substrate it experiences an additional
lift force due to the deformability of the substrate. In this work we find this lift force analytically …

Validity of Winkler's mattress model for thin elastomeric layers: beyond Poisson's ratio

TGJ Chandler, D Vella - Proceedings of the Royal …, 2020 - royalsocietypublishing.org
Winkler's mattress model is often used as a simplified model to understand how a thin elastic
layer, such as a coating, deforms when subject to a distributed normal load: the deformation …

Swimming trajectories of a three-sphere microswimmer near a wall

A Daddi-Moussa-Ider, M Lisicki, C Hoell… - The Journal of chemical …, 2018 - pubs.aip.org
The hydrodynamic flow field generated by self-propelled active particles and swimming
microorganisms is strongly altered by the presence of nearby boundaries in a viscous flow …
