Heat transfer analysis of MHD rotating flow of Fe₃O₄ nanoparticles through a stretchable surface

Abstract

The flow of a magnetite-H2O nanofluid has been considered among two rotating surfaces, assuming porosity in the upper plate. Furthermore, the lower surface is considered to move with variable speed to induce the forced convection. Centripetal as well as Coriolis forces impacting on the rotating fluid are likewise taken into account. Adequate conversions are employed for the transformation of the governing partial-differential equations into a group of non-dimensional ordinary-differential formulas. Numerical solution of the converted expressions is gained by means of the shooting technique. It is theoretically found that the nanofluid has less skin friction and advanced heat transport rate when compared with the base fluid. The effect of rotation causes the drag force to elevate and reduces the heat transport rate. Streamlines are portrayed to reveal the impact of injection/suction.

Entropy generation optimization of unsteady radiative hybrid nanofluid flow over a slippery spinning disk

“…They showed that carbon nanotube and Fe 3 O 4 -based nanocomposite exhibits effective heat transmission and thermal efficiency compared to single ferrite nanoparticles. Shahzad et al 41 investigated Fe 3 O 4 -H 2 O nanofluid behavior within two revolving disks considering the upper one as porous. They marked frictional amplification but heat transmission reduction for rotation.…”

“…Here, the influence of the embedded constraints on hybrid-class nanofluid flow are discussed and designated that hybrid-class nanofluids are the best thermal-conductor and play significant role in the circulation of blood in human body. Shahzad et al [6] analyzed MHD rotating flow of Fe 3 O 4 tiny-particles through stretchable obstacle with the manifestation of heat transfer. Here, Coriolis as well as centripetal forces taken into account.…”
