Penetrative phototactic bioconvection in an isotropic scattering suspension

, 2013
Phototaxis is a directed swimming response dependent upon the light intensity sensed by micro-organisms. Positive (negative) phototaxis denotes the motion directed towards (away from) the source of light.

High-temperature transport characteristics of magneto-micropolar nanofluid flow with microorganisms and stimulus energies: numerical insights

High Temperature Materials and Processes
Encouraged by many scientific and industrial uses of non-Newtonian nanofluids, this study investigates the two-dimensional convective hydromagnetic movement in a bioconvective micropolar nanofluid inside an elongating porous region with convective ...

Wavelengths of Bioconvection Patterns

, 1998
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.

Bioconvection in planctonic sea algae

, 1991
On the basis of experimental research bioconvection was for the first time discovered in three species of planctonic sea algae: Olisthodiscus luteus, Gymnodinium kowalewskii, Gymnodinium lanskaya.

Model of Lorenz instability for bioconvection

, 2010
Розвинено нелінійну модель Лоренца для дослідження критеріїв нестійкості біоконвективної течії для мікроорганізмів, рух яких регулюється силою ваги. На основі даної моделі визначені границі різних режимів руху середовища.

Emergent asymmetry in confined bioconvection

Journal of Fluid Mechanics
Bioconvection is the prototypical active matter system for hydrodynamic instabilities and pattern formation in suspensions of biased swimming microorganisms, particularly at the dilute end of the concentration spectrum where direct cell–cell interactions are less relevant.

Case Study on Homogeneous–Heterogeneous Chemical Reactions in a Magneto Hydrodynamics Darcy–Forchheimer Model with Bioconvection in Inclined Channels

Magnetochemistry
This study focuses on understanding the bioconvection in Jeffery–Hamel (JH) flow, which has valuable applications in areas like converging dies, hydrology, and the automotive industry, which make it a topic of practical importance.

Bioconvection in an anisotropic scattering suspension of phototactic algae

, 2013
Phototaxis is a directed swimming response dependent upon the light intensity sensed by microorganisms. Positive phototaxis denotes motion directed towards the source of light and negative phototaxis is motion directed away from it.
