Pairwise scattering and bound states of spherical microorganisms

C. Darveniza, T. Ishikawa, T. J. Pedley +1

The dynamic interactions between pairs of swimming microorganisms underpin the collective behaviour of larger suspensions, but accurately calculating pairwise collisions has typica…

Rheology of a concentrated suspension of spherical squirmers: monolayer in simple shear flow

T. Ishikawa, D. R. Brumley, T. J. Pedley

A concentrated, vertical monolayer of identical spherical squirmers, which may be bottom-heavy, and which are subjected to a linear shear flow, is modelled computationally by two d…

Stability of dancing Volvox

Takuji Ishikawa, T. J. Pedley, K. Drescher +1

Biflagellate algal cells of the genus Volvox form spherical colonies that propel themselves, vertically upwards in still fluid, by the coordinated beating of thousands of flagella,…

Stability of arrays of bottom-heavy spherical squirmers

Douglas R. Brumley, Timothy J. Pedley

The incessant swimming motion of microbes in dense suspensions can give rise to striking collective motions and coherent structures. However, theoretical investigations of these st…

Squirmers with swirl -- a model for swimming

T. J. Pedley, D. R. Brumley, R. E. Goldstein

Colonies of the green alga are spheres that swim through the beating of pairs of flagella on their surface somatic cells. The somatic cells themselves are mounted rigidly…

Metachronal waves in the flagellar beating of and their hydrodynamic origin

Douglas R. Brumley, Marco Polin, Timothy J. Pedley +1

Groups of eukaryotic cilia and flagella are capable of coordinating their beating over large scales, routinely exhibiting collective dynamics in the form of metachronal waves. The…

Dancing Volvox: Hydrodynamic Bound States of Swimming Algae

Knut Drescher, Kyriacos C. Leptos, Idan Tuval +3

The spherical alga Volvox swims by means of flagella on thousands of surface somatic cells. This geometry and its large size make it a model organism for studying the fluid dynamic…

Bacterial tracking of motile algae assisted by algal cell's vorticity field

Janos Tobias Locsei, Timothy J Pedley

Previously published experimental work by other authors has shown that certain motile marine bacteria are able to track free swimming algae by executing a zigzag path and steering…

Run and tumble chemotaxis in a shear flow: the effect of temporal comparisons and other complications

J. T. Locsei, T. J. Pedley

Escherichia coli is a motile bacterium that moves up a chemoattractant gradient by performing a biased random walk composed of alternating runs and tumbles. This paper presents cal…
