2006 journal article

Direct numerical simulation of settling of a large solid particle during bioconvection

INTERNATIONAL JOURNAL FOR NUMERICAL METHODS IN FLUIDS, 51(5), 511–530.

By: P. Geng* & A. Kuznetsov

author keywords: bioconvection; Chimera method; large particle; motile microorganisms; moving boundary; streamfunction-vorticity formulation; subgrid
TL;DR: It is demonstrated that bioconvection can either accelerate or decelerate settling of the particles depending on the initial position of the particle relative to the plume centre, and it is also shown that the particle impacts bioconvction plume by changing its shape and location in the chamber.

2005 journal article

Settling of bidispersed small solid particles in a dilute suspension containing gyrotactic micro-organisms

INTERNATIONAL JOURNAL OF ENGINEERING SCIENCE, 43(11-12), 992–1010.

By: P. Geng n & A. Kuznetsov

author keywords: bioconvection; small particles; sedimentation; motile micro-organisms
TL;DR: A bidispersed suspension of small solid particles that have different densities and settling velocities in a fluid that contains motile gyrotactic micro-organisms is considered and it is found that the number density distribution of solid particles of one type impacts that of particles of the other type as well as that of micro- organisms.
