Self-Propulsion of floating ice blocks caused by melting in water
Michael Berhanu, Amit Dawadi, Martin Chaigne +2
We show that floating ice blocks with asymmetric shapes can self-propel with significant speeds due to buoyancy driven currents caused by melting. In water baths with temperatures…
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…
Unstable invasion of sedimenting granular suspensions
Arshad Kudrolli, Rausan Jewel, Ram Sudhir Sharma +1
We investigate the development of mobility inversion and fingering when a granular suspension is injected radially between horizontal parallel plates of a cell filled with a miscib…
Micromechanics of intruder motion in wet granular medium
Rausan Jewel, Andreea Panaitescu, Arshad Kudrolli
We investigate the effective friction encountered by an intruder moving through a sedimented medium which consists of transparent granular hydrogels immersed in water, and the resu…
Shape and dynamics of seepage erosion in a horizontal granular bed
Michael Berhanu, Alexander Petroff, Olivier Devauchelle +2
We investigate erosion patterns observed in a horizontal granular bed resulting from seepage of water motivated by observation of beach rills and channel growth in larger scale lan…
Aggregation of frictional particles due to capillary attraction
Marie-Julie Dalbe, Darija Cosic, Michael Berhanu +1
Capillary attraction between identical millimeter sized spheres floating at a liquid-air interface and the resulting aggregation is investigated at low Reynolds number. We show tha…
