Flexible filaments buckle into helicoidal shapes in strong compressional flows
Brato Chakrabarti, Yanan Liu, John LaGrone +5
The occurrence of coiled or helical morphologies is common in nature, from plant roots to DNA packaging into viral capsids, as well as in applications such as oil drilling processe…
Complex dynamics of long, flexible fibers in shear
John LaGrone, Ricardo Cortez, Wen Yan +1
The macroscopic properties of polymeric fluids are inherited from the material properties of the fibers embedded in the solvent. The behavior of such passive fibers in flow has bee…
Elastohydrodynamics of swimming helices: effects of flexibility and confinement
John LaGrone, Ricardo Cortez, Lisa Fauci
Motivated by bacterial transport through porous media, here we study the swimming of an actuated, flexible helical filament in both three-dimensional free space and within a cylind…
Bistability in the synchronization of actuated microfilaments
Hanliang Guo, Lisa Fauci, Michael Shelley +1
Cilia and flagella are essential building blocks for biological fluid transport and locomotion at the micron scale. They often beat in synchrony and may transition between differen…
Rotational dynamics of a superhelix towed in a Stokes fluid
Sunghwan Jung, Kathleen Mareck, Lisa Fauci +1
Motivated by the intriguing motility of spirochetes (helically-shaped bacteria that screw through viscous fluids due to the action of internal periplasmic flagella), we examine the…
