Exploring the nanomechanical concepts of development through recent updates in magnetically guided system

Abstract

This article outlines an analytical analysis of unsteady mixed bioconvection buoyancy-driven nanofluid thermodynamics and gyrotactic microorganisms motion in the stagnation domain of the impulsively rotating sphere with convective boundary conditions. To make the equations physically realistic, zero mass transfer boundary conditions have been used. The Brownian motion and thermophoresis effects are incorporated in the nanofluid model. Magnetic dipole effect has been implemented. A system of partial differential equations is used to represent thermodynamics and gyrotactic microorganisms motion, which is then transformed into dimensionless ordinary differential equations. The solution methodology is involved by homotopy analysis method. The results obtained are based on the effect of dimensionless parameters on the velocity, temperature, nanoparticles concentration and density of the motile microorganisms profiles. The primary velocity increases as the mixed convection and viscoelastic parameters are increased while it decreases as the buoyancy ratio, ferro-hydrodynamic interaction and rotation parameters are increased. The secondary velocity decreases as viscoelastic parameter increases while it increases as the rotation parameter increases. Temperature is reduced as the Prandtl number and thermophoresis parameter are increased. The nanoparticles concentration is increased as the Brownian motion parameter increases. The motile density of gyrotactic microorganisms increases as the bioconvection Rayleigh number, rotation parameter and thermal Biot number are increased.

“…Hosseinzadeh et al [41] examined the ethylene glycol-based carbon nanotubes with thermal radiation, porosity, and entropy generation. The references [42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57] provide few other studies on nanofluid subject.…”

Consequence of Double‐Diffusion Convection and Partial Slip on Magneto‐Oldroyd‐4 Constants Nanofluids with Peristaltic Propulsion in an Asymmetric Channel

“…e bond of peristalsis with nanofluids has many utilizations in biomedical science (e.g., radiotherapy for cancer cure and drug delivery), chemical, and mechanical engineering (pumps and transportation of chemicals). Recently, such studies of nanoparticles along with different flow geometries have been examined extensively in physiological flows, such as references [27][28][29][30][31][32][33][34][35].…”
