Free-surface deformations induced by three-dimensional turbulence
Michaël Berhanu, Eric Falcon
We report the experimental characterization of free-surface deformations generated by three-dimensional homogeneous and isotropic turbulence. Using Fourier transform profilometry i…
Experimental study of three-dimensional turbulence under a free surface
Timothée Jamin, Michael Berhanu, Eric Falcon
In many environmental flows, an air-water free surface interacts with a turbulent flow in the water phase. To mimic this situation, we propose an original experimental setup, based…
Dissolution-driven propulsion of floating solids
Martin Chaigne, Michael Berhanu, Arshad Kudrolli
We show that unconstrained asymmetric dissolving solids floating in a fluid can move rectilinearly as a result of attached density currents which occur along their inclined surface…
Emergence of tip singularities in dissolution patterns
Martin Chaigne, Sabrina Carpy, Marion Massé +3
Chemical erosion, one of the two major erosion processes along with mechanical erosion, occurs when a soluble rock like salt, gypsum or limestone is dissolved in contact with a wat…
Wave spectroscopy in a driven granular material
Michael Berhanu, Simon Merminod, Gustavo Castillo +1
Driven granular media constitute model systems in out-of-equilibrium statistical physics. By assimilating the motions of granular particles to those of atoms, by analogy, one can o…
Alcove formation in dissolving cliffs driven by density inversion instability
Ram Sudhir Sharma, Michael Berhanu, Arshad Kudrolli
We demonstrate conditions that give rise to cave-like features commonly found in dissolving cliffsides with a minimal two-phase physical model. Alcoves that are wider at the top an…
