Squirmer hydrodynamics near a periodic surface topography
Kenta Ishimoto, Eamonn A. Gaffney, David J. Smith
The behaviour of microscopic swimmers has previously been explored near large scale confining geometries and in the presence of very small-scale surface roughness. Here we consider…
Control and controllability of microswimmers by a shearing flow
Clément Moreau, Kenta Ishimoto, Eamonn A. Gaffney +1
With the continuing rapid development of artificial microrobots and active particles, questions of microswimmer guidance and control are becoming ever more relevant and prevalent.…
Efficient simulation of filament elastohydrodynamics in three dimensions
Benjamin J. Walker, Kenta Ishimoto, Eamonn A. Gaffney
Fluid-structure simulations of slender inextensible filaments in a viscous fluid are often plagued by numerical stiffness. Recent coarse-graining studies have reduced the computati…
The pairwise hydrodynamic interactions of synchronized spermatozoa
Benjamin J. Walker, Kenta Ishimoto, Eamonn A. Gaffney
The journey of mammalian spermatozoa in nature is well-known to be reliant on their individual motility. Often swimming in crowded microenvironments, the progress of any single swi…
Filament mechanics in a half-space via regularised Stokeslet segments
Benjamin J. Walker, Kenta Ishimoto, Hermes Gadêlha +1
We present a generalisation of efficient numerical frameworks for modelling fluid-filament interactions via the discretisation of a recently-developed, non-local integral equation…
The N-flagella problem: Elastohydrodynamic motility transition of multi-flagellated bacteria
Kenta Ishimoto, Eric Lauga
Peritrichous bacteria such as Escherichia coli swim in viscous fluids by forming a helical bundle of flagellar filaments. The filaments are spatially distributed around the cell bo…
