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…
