Scientific Reports, 2021 Bioconvection has recently been the subject of dispute in a number of biotechnological fields that depend on fluids and their physical properties. When mixed nanofluids are subjected to heat and mass transmission, the process of bioconvection occurs ...

Numerical Analysis of Bioconvection Generated by Chemotactic Bacteria
Journal of Fluid Science and Technology, 2009 Numerical simulations were carried out modeling the bioconvection generated by chemotactic bacteria in a shallow chamber, and the influence of the Rayleigh number on bioconvection was examined.

A tale of three taxes: photo-gyro-gravitactic bioconvection [PDF]
, 2011 The term bioconvection encapsulates the intricate patterns in concentration, due to hydrodynamic instabilities, that may arise in suspensions of non-neutrally buoyant, biased swimming microorganisms. The directional bias may be due to light (phototaxis),

Penetrative phototactic bioconvection [PDF]
Physics of Fluids, 2005 Using the generic model of Vincent and Hill [J. Fluid Mech. 327, 343 (1996)] for phototaxis in a suspension of swimming algae, we investigate two-dimensional phototactic bioconvection in a suspension confined between a rigid bottom boundary, and stress-free top and lateral boundaries.

Nanofluid Bioconvection in Porous Enclosure with Viscous Dissipation [PDF]
, 2022 In this paper, the bioconvective nanofluid flow in porous square enclosure containing oxytactic microorganism associated with viscous dissipation, is discussed. The bioconvection flow in porous medium is framed by Darcy-Boussinesq approximation. Galerkin

Analytical approximations for the orientation distribution of small dipolar particles in steady shear flows [PDF]
, 1998 Analytic approximations are obtained to solutions of the steady Fokker-Planck equation describing the probability density functions for the orientation of dipolar particles in a steady, low-Reynolds-number shear flow and a uniform external field.

The orientation of swimming bi-flagellates in shear flows [PDF]
, 2012 Biflagellated algae swim in mean directions that are governed by their environments. For example, many algae can swim upward on average (gravitaxis) and toward downwelling fluid (gyrotaxis) via a variety of mechanisms.
