Analogy between streamers in sinking spheroids, gyrotactic plumes and chemotactic collapse
Lloyd Fung
In a dilute suspension where sinking spheroids or motile gyrotactic microorganisms are modelled as orientable and negatively buoyant particles, we have found analytical solutions t…
A local approximation model for macroscale transport of biased active Brownian particles in a flowing suspension
Lloyd Fung, Rachel N. Bearon, Yongyun Hwang
A dilute suspension of motile microorganisms subjected to a strong ambient flow, such as algae in the ocean, can be modelled as a population of non-interacting, orientable active B…
A sequence of transcritical bifurcations in a suspension of gyrotactic microswimmers in vertical pipe
Lloyd Fung, Yongyun Hwang
Kessler (Nature, vol. 313, 1985, pp. 218-220) first showed that plume-like structures spontaneously appear from both stationary and flowing suspensions of gyrotactic microswimmers…
Bifurcation and stability of downflowing gyrotactic micro-organism suspensions in a vertical pipe
Lloyd Fung, Rachel N. Bearon, Yongyun Hwang
In the experiment that first demonstrated gyrotactic behaviour of bottom-heavy swimming microalgae (e.g. Chlamydomonas), Kessler (Nature, vol. 313, 1985, pp. 218-220) showed that a…
Instability of tilted shear flow in a strongly stratified and viscous medium
Lloyd Fung, Yongyun Hwang
A linear stability analysis is performed on a tilted parallel wake in a strongly stratified fluid at low Reynolds numbers. A particular emphasis of the present study is given to th…
