Thin-film drainage becomes singular at saddles
Simeon Djambov, Alice Marcotte, François Gallaire +1
From coating curved parts to creeping lava, thin-film gravitational drainage over complex surfaces can produce abrupt accumulation, usually associated with sharp edges or defects.…
Deformation and stability of a gas bubble in a biaxial straining flow
Aliénor Rivière, David Fabre, Jacques Magnaudet +1
Taking advantage of the recently developed L-ALE framework [Sierra-Ausin \textit{et al.}, Phys. Rev. Fluids {\bf{7}}, 113603 (2022)], we characterize the linear dynamics of an inco…
Lagrangian vs Eulerian view on the mean drift and streaming flows in orbital sloshing
Alessandro Bongarzone, François Gallaire
Orbital sloshing is a technique to gently mix a container's liquid content and it is commonly used in fermentation and cell cultivation processes. Besides the rich wave dynamics ob…
Tumbling elimination induced by permeability: an experimental approach
Jesús Sánchez-Rodríguez, François Gallaire
Archetypal falling behaviors of impervious objects are classified into four modes: fluttering, tumbling, steady descent and chaotic motion. The classical scenario predicts these be…
Stick-slip-to-stick transition of liquid oscillation in a U-tube
Alessandro Bongarzone, François Gallaire
The nonlinear decay of oscillations of a liquid column in a U-shaped tube is investigated within the theoretical framework of the projection method formalized by Bongarzone et al.…
Gravity-driven coatings on curved substrates: a differential geometry approach
Pier Giuseppe Ledda, Matteo Pezzulla, Etienne Jambon-Puillet +2
Although the drainage and spreading processes of thin liquid films on substrates have received growing attention during the last decades, the study of three-dimensional cases is li…
The effects of spanwise confinement on stratified shear instabilities
Yves-Marie Ducimetière, François Gallaire, Adrien Lefauve +1
We consider the influence of transverse confinement on the instability properties of velocity and density distributions reminiscent of those pertaining to exchange flows in stratif…
Leidenfrost flows: instabilities and symmetry breakings
Eunok Yim, Ambre Bouillant, David Quéré +1
Leidenfrost drops were recently found to host strong dynamics. In the present study, we investigate both experimentally and theoretically the {flows structures and stability} insid…
Transport of flexible fibers in confined micro-channels
Jean Cappello, Mathias Bechert, Camille Duprat +3
When transported in confined geometries rigid fibers show interesting transport dynamics induced by friction with the top and bottom walls. Fiber flexibility causes an additional c…
Oscillations of confined fibers transported in microchannels
Mathias Nagel, Pierre-Thomas Brun, Helene Berthet +3
We investigate the trajectories of rigid fibers as they are transported in a pressure-driven flow, at low Reynolds number, in shallow Hele Shaw cells. The transverse confinement an…
Breaking anchored droplets in a microfluidic Hele-Shaw cell
Gabriel Amselem, P. T. Brun, François Gallaire +1
We study microfluidic self digitization in Hele-Shaw cells using pancake droplets anchored to surface tension traps. We show that above a critical flow rate, large anchored droplet…
Rayleigh-Taylor instability under an inclined plane
P. -T Brun, Adam Damiano, Pierre Rieu +2
We revisit the canonical Rayleigh-Taylor instability and investigate the case of a thin film of fluid upon the underside of an inclined plane. The presence of a natural flow along…
