Hydrodynamic Resistance on Oscillating Planar Interfacial Bodies
Ian Ho, Ajay Harishankar Kumar, Daniel M. Harris
We study the unsteady dynamics of floating planar bodies undergoing lateral oscillations along an air-water interface. Scaling arguments indicate that at high Womersley number and…
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…
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…
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…
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…
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…
