Dancing rivulets in an air-filled Hele-Shaw cell
Grégoire Le Lay, Adrian Daerr
We study the behaviour of a thin fluid filament (a rivulet) flowing in an air-filled Hele-Shaw cell. Transverse and longitudinal deformations can propagate on this rivulet, althoug…

Phase-Locking Parametric Instability Coupling Longitudinal and Transverse Waves on Rivulets in a Hele-Shaw Cell
Grégoire Le Lay, Adrian Daerr
We report an instability exhibited by a fluid system when coupling two distinct types of waves, both linearly damped. While none of them is unstable on its own, they amplify one an…

Magnetic levitation in the field of a rotating dipole
Grégoire Le Lay, Sarah Layani, Adrian Daerr +5
It is well known that two permanent magnets of fixed orientation will either always repel or attract one another regardless of the distance between them. However, if one magnet is…
