Analysis and modeling of the inverted bioconvection in Chlamydomonas reinhardtii: emergence of plumes from the layer of accumulated cells

Heliyon, 2018
Bioconvection is a convective flow found in a suspension of motile cells that swim against gravity, and is a primitive form of order formation of cells, which has been studied both experimentally and theoretically.

Time-reproductive solutions for a bioconvective flow [PDF]

Annali di Matematica Pura ed Applicata, 2012
We consider the existence and uniqueness of periodic solutions for the generalized bioconvective flow, which is a well known model to describe the convection caused by the concentration of upward swimming microorganism in a fluid.

Bioconvection in spatially extended domains

Physical Review E, 2013
We numerically explore gyrotactic bioconvection in large spatially extended domains of finite depth using parameter values from available experiments with the unicellular alga Chlamydomonas nivalis. We numerically integrate the three-dimensional, time-dependent continuum model of Pedley et al. [J. Fluid Mech.
