Hall current and morphological effects on MHD micropolar non-Newtonian tri-hybrid nanofluid flow between two parallel surfaces

Abstract

In the present work, the magnetohydrodynamic flow and heat transfer of a micropolar tri-hybrid nanofluid between two porous surfaces inside a rotating system has been examined. A tri-hybrid nanofluid is a new idea in the research area, which gives a better heat transfer rate as compared to hybrid nanofluid and nanofluid. We also incorporated the thermal radiation effects and Hall current in this article. The similarity techniques are used to reduce the governing nonlinear PDEs to a set of ODEs. For the numerical solution of the considered problem, we have used the MATLAB-based Bvp4c method. The results are presented for tri-hybrid Fe3O4-Al2O3-TiO2/H2O nanofluid. The main focus of this study is to examine the magnetohydrodynamic heat transfer and tri-hybrid nanofluid flow in a rotating system between two orthogonal permeable plates by taking into account the Hall current and thermal radiation effects. The obtained results have been explained with the help of graphical illustrations and tables. It is observed that the heat transfer rate of tri-hybrid nanofluid is greater than as compared to hybrid nanofluid and nanofluid. The increasing behavior is also noticed in micro rotational velocity for augmented values of $${R}_{0}$$ R 0 , $$Ha,$$ H a , and $$\beta$$ β . The larger values of $${\phi }_{1}$$ ϕ 1 , $${\phi }_{2}$$ ϕ 2 , and $${\phi }_{3}$$ ϕ 3 result in the decrement of SFC and increment in Nusselt number in both (suction and injection) cases.

Unsteady MHD Casson Fluid Flow through Infinite Inclined Plate in the Presences of Hall Current and Chemical Reaction

“…After detailed study, the noticed that there is a growth in the velocity profile for 0   , while the velocity is reduced with growing values of magnetic parameter and for negative values of  . Rauf et al, [14] attracted to study the magnetohydrodynamic flow and heat transfer of a micropolar tri-hybrid nanofluid between two porous surfaces inside a rotating system with the hall currents and morphological effects. The results from their studies shows the heat transfer rate of tri-hybrid nanofluid is greater than as compared to hybrid nanofluid and nanofluid.…”
