A bi-directional low-Reynolds-number swimmer with passive elastic arms

Jessie Levillain, François Alouges, Antonio Desimone +3

It has been recently shown that it is possible to design simple artificial swimmers at low Reynoldsnumber that possess only one degree of freedom and, nevertheless, can overcome Pu…

Orientational dynamics and rheology of active suspensions in weakly viscoelastic flows

Akash Choudhary, Sankalp Nambiar, Holger Stark

Microswimmer suspensions in Newtonian fluids exhibit unusual macroscale properties, such as a superfluidic behavior, which can be harnessed to perform work at microscopic scales. S…

The hydrodynamics of slender swimmers near deformable interfaces

Sankalp Nambiar, John S Wettlaufer

We study the coupled hydrodynamics between a motile slender microswimmer and a deformable interface that separates two Newtonian fluid regions. From the disturbance field generated…

Shear induced migration of microswimmers in pressure-driven channel flow

LaxminarsimhaRao V., Sankalp Nambiar, Ganesh Subramanian

We study the shear induced migration of microswimmers (primarily, active Brownian particles or ABP's) in a plane Poiseuille flow. For wide channels characterized by $U_b/HD_r \ll 1…

Enhanced velocity fluctuations in interacting swimmer suspensions

Sankalp Nambiar, Piyush Garg, Ganesh Subramanian

A dilute non-interacting suspension of micro-swimmers exhibits a finite velocity variance and short-ranged correlations that decay over a swimmer length. For a suspension of intera…

Stress relaxation in a dilute bacterial suspension: The active-passive transition

Sankalp Nambiar, Phanikanth S, Nott P. R. +1

We analyse the time dependent non-linear rheology of a dilute bacterial suspension (e.g. E. coli) for a pair of impulsively started linear flows - simple shear and uniaxial extensi…
