Helical trajectories of swimming cells with a flexible flagellar hook
Zonghao Zou, Wilson Lough, Saverio E. Spagnolie
The flexibility of the bacterial flagellar hook is believed to have substantial consequences for microorganism locomotion. Using a simplified model of a rigid flagellum and a flexi…
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…
Comparative hydrodynamics of bacterial polymorphism
Saverio E. Spagnolie, Eric Lauga
Most bacteria swim through fluids by rotating helical flagella which can take one of twelve distinct polymorphic shapes. The most common helical waveform is the "normal" form, used…
Stokesian jellyfish: Viscous locomotion of bilayer vesicles
Arthur A. Evans, Saverio E. Spagnolie, Eric Lauga
Motivated by recent advances in vesicle engineering, we consider theoretically the locomotion of shape-changing bilayer vesicles at low Reynolds number. By modulating their volume…
The optimal elastic flagellum
Saverio E. Spagnolie, Eric Lauga
Motile eukaryotic cells propel themselves in viscous fluids by passing waves of bending deformation down their flagella. An infinitely long flagellum achieves a hydrodynamically op…
