MHD biconvective flow of Powell Eyring nanofluid over stretched surface
AIP Advances, 2017 The present work is focused on behavioral characteristics of gyrotactic microorganisms to describe their role in heat and mass transfer in the presence of magnetohydrodynamic (MHD) forces in Powell-Eyring nanofluids.

On the equations of bioconvective flow
Kyoto Journal of Mathematics, 1992 The bioconvective flow in a culture fluid due to the concentration of moving microorganisms in the fluid is considered. The basic equations are the equations of motion of the fluid and the concentration of the microorganisms. It is shown that a solution of the equations of equilibrium with given initial concentration exists and this solution is ...

Bioconvection in a suspension of phototactic algae [PDF]
Journal of Fluid Mechanics, 1996 In this paper we develop a new generic model for phototaxis in a suspension of microscopic swimming algae. Phototaxis is a directed swimming response dependent upon the light conditions sensed by the microorganisms. Positive phototaxis consists of motions directed toward the source of illumination and negative phototaxis is motion directed away from it.

Bioconvection pattern of Euglena under periodical illumination
Frontiers in Cell and Developmental Biology, 2023 Microorganisms respond to environmental conditions and often spontaneously form highly ordered convection patterns. This mechanism has been well-studied from the viewpoint of self-organization. However, environmental conditions in nature are usually dynamic. Naturally, biological systems respond to temporal changes in environmental condition.
