Bioconvection

Fluid Dynamics Research, 2005
Summary: Bioconvection patterns are usually observed in the laboratory in shallow suspensions of randomly, but on average upwardly, swimming micro-organisms which are a little denser than water, but have also been found in situ in micropatches of zooplankton [\textit{U. Kils}, Bull. Mar. Sci. 53, 160--169 (1993)].

Wavelengths of Bioconvection Patterns

Journal of Experimental Biology, 1997
ABSTRACT Bioconvection occurs as the result of the collective behaviour of many micro-organisms swimming in a fluid and is realised as patterns similar to those of thermal convection which occur when a layer of water is heated from below.

Axisymmetric Bioconvection in a Cylinder

Journal of Theoretical Biology, 2002
In three-dimensional bioconvection, the regions of rising and sinking fluid are dissimilar. This geometrical effect is studied for axisymmetric bioconvection in a cylindrical cell with stress-free (i.e. normal velocity and tangential stress vanish) lateral and top boundaries, and rigid bottom boundary. Using the continuum model of Pedley et al.
