Data_Sheet_1_Emergence of a Euglena bioconvection spot controlled by non-uniform light.PDF

, 2023
Microorganisms possess taxes, which are the behavioral response to stimuli. The interaction between taxis and fluid dynamic instability leads to a macroscopic flow called bioconvection.

Computational Analysis of Prandtl on the Fluid Relaxation Time Features for the Energy and Concentration Nanomaterial Flow of Motile Microorganisms Induced by a Deformable Sheet With Chemical Reactions

International Journal of Differential Equations, Volume 2026, Issue 1, 2026.
This study investigates the phenomenon of bioconvection in a Darcy–Forchheimer flow of a Prandtl fluid on a stretching sheet, considering dual diffusive processes and incorporating the Cattaneo–Christov heat conduction model. For the conversion of modeled equations to dimensionless, a suitable set of variables has been incorporated.

Magneto‐Hydrothermal and Entropy Analysis of Double‐Diffusive Convection in a Nano‐Encapsulated PCM‐Suspended Elliptical Pipes Thermal Storage Tank: Impact of Exothermic Reaction

Energy Science &Engineering, Volume 13, Issue 12, Page 5882-5909, December 2025.
ABSTRACT PCMs store thermal energy during phase transitions without temperature changes, making them valuable for various thermal applications. When direct PCM use isn't practical, researchers have developed encapsulation methods as an alternative approach.

A two-dimensional Darcy–Forchheimer mathematical model for bioconvection flow with microbial exoprotein activity

South African Journal of Science
Microbes play a pivotal role in heat and mass transfer in boundary layer flow. These microbes are added to nanofluids to promote efficiency and the desired fluid properties. Some microbes excrete exoproteins into the solution, which significantly affect

Wavelengths in bioconvection patterns [PDF]

, 2016
Unicellular bottom-heavy swimming microorganisms are usually denser than the fluid in which they swim. In shallow suspensions, the bottom heaviness results in a gravitational torque that orients the cells to swim vertically upwards in the absence of ...
