Elasto-Hydrodynamic Propulsion of a Magnetically Actuated Filament
Sohum Kapadia, Julien Chopin, Arshad Kudrolli
We investigate the low-Reynolds-number propulsion of a slender elastic filament with a dipolar magnetic head actuated by an oscillating field in a viscous fluid by studying its str…
Dynamical Boundary Following and Corner Trapping of Undulating Worms
Sohum Kapadia, Arshad Kudrolli
We investigate the behavior of {\it Lumbriculus variegatus} in circular and polygonal chambers and show that the worms align with the boundaries as they move forward and then becom…
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…
Memory in cyclically crumpled sheets
Amit Dawadi, Arshad Kudrolli
We investigate the crumpling of a sheet as it is repeatedly crushed onto itself by rolling it into a cylinder and twisting it axially while allowing the end-to-end length to evolve…
Bundling architecture in elastic filaments with applied twist
Amit Dawadi, Animesh Biswas, Julien Chopin +1
We investigate the formation of helical multifilament bundles and the torque required to achieve them as a function of applied twist. Hyperelastic filaments with circular cross sec…
