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 …

Rotation of an immersed cylinder sliding near a thin elastic coating

B Rallabandi, B Saintyves, T Jules, T Salez… - Physical Review …, 2017 - APS
It is known that an object translating parallel to a soft wall in a viscous fluid produces
hydrodynamic stresses that deform the wall, which in turn results in a lift force on the object …
