Vertical motion of a periodically driven floating disc
Anand U. Oza, Jack-William Barotta, Eli Silver +1
We present the results of a combined theoretical and experimental investigation into the vertical dynamics of floating discs subjected to an imposed time-periodic forcing. The axis…
The physics of cranberry bogs
Caroline M. Barotta, Jack-William Barotta
The common New England sight of a cranberry bog presents a rich tapestry of fluid dynamics and soft matter phenomena. Here, we present four connected problems exploring the behavio…
Macroscopic Brownian Motion on a Chaotic Fluid Interface
Jack-William Barotta, Caroline M. Barotta, Eli Silver +1
Brownian motion is the erratic motion of an object due to collisions with the fluid in which it is immersed. In this work, we detail a tabletop laboratory demonstration of underdam…
Propulsion and interaction of wave-propelled interfacial particles
Daniel M. Harris, Jack-William Barotta
When a floating body is internally or externally vibrated, its self-generated wavefield can lead to steady propulsion along the interface. In this article, we review several relate…
Drop rebound at low Weber number
Chase T. Gabbard, Elvis A. Aguero, Radu Cimpeanu +5
We study the rebound of drops impacting non-wetting substrates at low Weber number through experiment, direct numerical simulation, and reduced-order modeling. Submillimeter-s…
Synchronization and self-assembly of free capillary spinners
Nilgun Sungar, John Sharpe, Loic Ijzerman +1
Chiral active particles are able to draw energy from the environment to self-propel in the form of rotation. We describe an experimental arrangement wherein chiral objects, spinner…
Synchronization of wave-propelled capillary spinners
Jack-William Barotta, Giuseppe Pucci, Eli Silver +2
When a millimetric body is placed atop a vibrating liquid bath, the relative motion between the object and interface generates outward propagating waves with an associated momentum…
Mermaid Cereal: Interactions and Pattern Formation in a Macroscopic Magnetocapillary SALR System
Alireza Hooshanginejad, Jack-William Barotta, Victoria Spradlin +3
When particles are deposited at a fluid interface they tend to aggregate by capillary attraction to minimize the overall potential energy of the system. In this work, we embed floa…
Non-equilibrium thermodynamics in driven macroscopic self-assembly
Stuart J. Thomson, Jack-William Barotta, Daniel M. Harris
Equilibrium statistical mechanics provides a robust framework for characterizing phase transitions in systems whose microsopic dynamics are time-reversible. Efforts to develop and…
Bidirectional Wave-Propelled Capillary Spinners
Jack-William Barotta, Stuart J. Thomson, Luke F. L. Alventosa +2
When a solid body floats at the interface of a vibrating liquid bath, the relative motion between the object and interface generates outwardly propagating surface waves. It has rec…
