Phoretic flow induced by asymmetric confinement
(Cambridge University PressJournal of Fluid Mechanics, 2016-06-28)
Internal phoretic flows due to the interactions of solid boundaries with local chemical gradients may be created using chemical patterning. Alternatively, we demonstrate here that internal flows might also be induced by ...
Bacterial Hydrodynamics
(Annual ReviewsAnnual Review of Fluid Mechanics, 2016)
Bacteria predate plants and animals by billions of years. Today, they are the
world’s smallest cells, yet they represent the bulk of the world’s biomass
and the main reservoir of nutrients for higher organisms. Most bacteria ...
Helical propulsion in shear-thinning fluids
(Cambridge University PressJournal of Fluid Mechanics, 2017-02-01)
Swimming micro-organisms often have to propel themselves in complex non-Newtonian fluids. We carry out experiments with self-propelling helical swimmers driven by an externally rotating magnetic field in shear-thinning ...
