Slender-ribbon theory
(American Institute of PhysicsPhysics of Fluids, 2016-01-11)
Ribbons are long narrow strips possessing three distinct material length scales (thickness, width, and length) which allow them to produce unique shapes unobtainable by wires or filaments. For example, when a ribbon has ...
Hydrodynamic interactions between nearby slender filaments
(IOP PublishingEPL (Europhysics Letters), 2016-11-28)
Cellular biology abound with filaments interacting through fluids, from intracellular microtubules, to rotating flagella and beating cilia. While previous work has demonstrated the complexity of capturing nonlocal hydrodynamic ...
Rotation of slender swimmers in isotropic-drag media
(American Physical SocietyPhysical Review E, 2016)
The drag anisotropy of slender filaments is a critical physical property allowing swimming in low-Reynolds number flows, and without it linear translation is impossible. Here we show that, in contrast, net rotation can ...
