Fluid mechanics

During my PhD, I worked on the dynamics of liquid rivulets in Hele-Shaw cell. This led to the following articles:

Grégoire Le Lay & Adrian Daerr,
Dancing rivulets in an air-filled Hele-Shaw cell,
Under review at J. Fluid Mech.

Grégoire Le Lay & Adrian Daerr,
Controlling and characterizing thin films with high resolution,
[Featured Article] Physics of Fluids, 37, 062101 (2025) | 10.1063/5.0268672 | PDF

Grégoire Le Lay & Adrian Daerr,
Phase-locking parametric instability coupling longitudinal and transverse waves,
Physical Review Letters, 134, 014001 (2025) | 10.1103/PhysRevLett.134.014001 | PDF

During an internship in Anne Juel’s group at MCND, I worked on an experimental setup aiming at capturing the complex dynamics of air bubbles in a channel presenting a geometrical constriction:

Mechanics

I wrote a model for an intriguing problem, which began as a student’s project, and proved to be much deeper than anticipated:

Magnetic levitation in the field of a rotating dipole,
