Jeffery's orbits and microswimmers in flows: A theoretical review

K Ishimoto - Journal of the Physical Society of Japan, 2023 - journals.jps.jp
In this review, we provide a theoretical introduction to Jeffery's equations for the orientation
dynamics of an axisymmetric object in a flow at low Reynolds number, and review recent …

Generalised Jeffery's equations for rapidly spinning particles. Part 2. Helicoidal objects with chirality

MP Dalwadi, C Moreau, EA Gaffney… - Journal of Fluid …, 2024 - cambridge.org
In this two-part study, we investigate the motion of rigid, active objects in shear Stokes flow,
focusing on bodies that induce rapid rotation as part of their activity. In Part 2, we derive and …

Cell aspect ratio important for bacterial rheotaxis

J Zhong, X Xu - Physics of Fluids, 2025 - pubs.aip.org
When placed in flows with local shear, flagellated bacteria commonly display reorientations
toward the local vorticity direction, a chirality-induced rheotactic behavior of great …

Generalised Taylor dispersion of chiral microswimmers

K Ogawa, K Ishimoto - arxiv preprint arxiv:2403.08201, 2024 - arxiv.org
Transport phenomena of microswimmers in fluid flows play a crucial role in various
biological processes, including bioconvection and cell sorting. In this paper, we investigate …
