The sedimentation of flexible filaments: Trajectories, particle clouds and a buckling instability
Harishankar Manikantan, Lei Li, David Saintillan +1
In this fluid dynamics video we explore an array of different possible dynamics for a flexible filament sedimenting in a viscous fluid. The time-dependent shapes and trajectories o…
Locomotion of helical bodies in viscoelastic fluids: enhanced swimming at large helical amplitudes
Saverio E. Spagnolie, Bin Liu, Thomas R. Powers
The motion of a rotating helical body in a viscoelastic fluid is considered. In the case of force-free swimming, the introduction of viscoelasticity can either enhance or retard th…
The sedimentation of flexible filaments
Lei Li, Harishankar Manikantan, David Saintillan +1
The dynamics of a flexible filament sedimenting in a viscous fluid are explored analytically and numerically. Compared to the well-studied case of sedimenting rigid rods, the intro…
