Microscale flow dynamics of ribbons and sheets
(Royal Society of ChemistrySoft Matter, 2017-01-18)
Numerical study of the hydrodynamics of thin sheets and ribbons presents difficulties associated with resolving multiple length scales. To circumvent these difficulties, asymptotic methods have been developed to describe ...
Autophoretic flow on a torus
(American Physical SocietyPhysical Review Fluids, 2017-03-02)
Phoretic swimmers provide new avenues to study nonequilibrium statistical physics and are also hailed as a promising technology for bioengineering at the cellular scale. Exact solutions for the locomotion of such swimmers ...
Analytical solutions to slender-ribbon theory
(Physical Review Fluids, 2017-08-01)
Bundling of elastic filaments induced by hydrodynamic interactions
(Physical Review Fluids, 2017-12-01)
Peritrichous bacteria swim in viscous fluids by rotating multiple helical flagellar filaments. As the bacterium swims forward, all its flagella rotate in synchrony behind the cell in a tight helical bundle. When the bacterium ...
Active particles in periodic lattices
(Institute of Physics (IoP) and Deutsche Physikalische GesellschaftNew Journal of Physics, 2017-11-01)
Both natural and artificial small-scale swimmers may often self-propel in environments subject to complex geometrical constraints. While most past theoretical work on low-Reynolds number locomotion addressed idealised ...
Leading-order Stokes flows near a corner
(OUPIMA Journal of Applied Mathematics (Institute of Mathematics and Its Applications), 2018-07-25)
Singular solutions of the Stokes equations play important roles in a variety of fluid dynamics problems. They allow the calculation of exact flows, are the basis of the boundary integral methods used in numerical computations, ...
Autophoretic motion in three dimensions.
(RSCSoft matter, 2018-05)
Janus particles with the ability to move phoretically in self-generated chemical concentration gra- dients are model systems for active matter. Their motion typically consists of straight paths with rotational diffusion ...
