Report

Sedimentation of elongated non-motile prolate spheroids in homogenous isotropic turbulence

Autor: Ardekani, M. Niazi, Sardina, G., Brandt, L., Karp-Boss, L., Bearon, R. N., Variano, E. A.

Phytoplankton are the foundation of aquatic food webs. Through photosynthesis, phytoplankton draw down CO2 at magnitudes equivalent to forests and other terrestrial plants and convert it to organic material that is then consumed by other organisms of

Gyrotactic swimmer dispersion in pipe flow: testing the theory

Autor: Croze, O. A., Bearon, R. N., Bees, M. A.

Publikováno v: J. Fluid Mech. Vol. 113, 481-506 (2017)

Suspensions of microswimmers are a rich source of fascinating new fluid mechanics. Recently we predicted the active pipe flow dispersion of gyrotactic microalgae, whose orientation is biased by gravity and flow shear. Analytical theory predicts that

Report

Biased swimming cells do not disperse in pipes as tracers: a population model based on microscale behaviour

Autor: Bearon, R. N., Bees, M. A., Croze, O. A.

Publikováno v: Phys. Fluids, vol 24, 121902 (2012)

There is much current interest in modelling suspensions of algae and other micro-organisms for biotechnological exploitation, and many bioreactors are of tubular design. Using generalized Taylor dispersion theory, we develop a population-level swimmi
