Exact solutions for hydrodynamic interactions of two squirming spheres
- PhysicsJournal of Fluid Mechanics
- 2017
We provide exact solutions of the Stokes equations for a squirming sphere close to a no-slip surface, both planar and spherical, and for the interactions between two squirmers, in three dimensions.…
Wall-curvature driven dynamics of a microswimmer
- PhysicsPhysical Review Fluids

Microorganisms navigate through fluid, often confined by complex environments, to survive and sustain life. Inspired by this fact, we consider a model system and seek to understand the wall curvature…
Modeling chemo-hydrodynamic interactions of phoretic particles: A unified framework
- PhysicsPhysical Review Fluids

The swimming behavior of self-propelled microorganisms is studied by particle-based mesoscale simulations and single active squirmers show a persistent random-walk behavior, determined by forward motion, lateral diffusion, and orientational fluctuations, in agreement with theoretical predictions.

Recent work has identified persistent cluster states which were shown to be assembled and held together by hydrodynamic interactions alone [Driscoll \textit{et al.} (2017) Nature Physics, 13(4),…
A new continuum model for suspensions of gyrotactic micro-organisms
- PhysicsJournal of Fluid Mechanics

The continuum model for small epsilon is used to reanalyse the instability of a uniform suspension and it is demonstrated that the only significant contribution to sigma is that derived from the stresslets associated with the cells' intrinsic swimming motions.
