Heat Transfer Attributes of Gold–Silver–Blood Hybrid Nanomaterial Flow in an EMHD Peristaltic Channel with Activation Energy

Nanomaterials, 2022
The heat enhancement in hybrid nanofluid flow through the peristaltic mechanism has received great attention due to its occurrence in many engineering and biomedical systems, such as flow through canals, the cavity flow model and biomedicine.

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.

Analysis and modeling of the inverted bioconvection in Chlamydomonas reinhardtii: emergence of plumes from the layer of accumulated cells

Heliyon, 2018
Bioconvection is a convective flow found in a suspension of motile cells that swim against gravity, and is a primitive form of order formation of cells, which has been studied both experimentally and theoretically.

Time-reproductive solutions for a bioconvective flow [PDF]

Annali di Matematica Pura ed Applicata, 2012
We consider the existence and uniqueness of periodic solutions for the generalized bioconvective flow, which is a well known model to describe the convection caused by the concentration of upward swimming microorganism in a fluid.

Impact of double-diffusive convection and motile gyrotactic microorganisms on magnetohydrodynamics bioconvection tangent hyperbolic nanofluid

Open Physics, 2020
The double-diffusive tangent hyperbolic nanofluid containing motile gyrotactic microorganisms and magnetohydrodynamics past a stretching sheet is examined. By adopting the scaling group of transformation, the governing equations of motion are transformed

Bioconvection in spatially extended domains

Physical Review E, 2013
We numerically explore gyrotactic bioconvection in large spatially extended domains of finite depth using parameter values from available experiments with the unicellular alga Chlamydomonas nivalis. We numerically integrate the three-dimensional, time-dependent continuum model of Pedley et al. [J. Fluid Mech.

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.
