Abstract:In this article, the magnetohydrodynamic flow and heat transmission of a micropolar hybrid nanofluid between two surfaces inside a rotating system are examined. The Hall current and thermal radiations are also considered for the flow system. In this article, a base fluid is taken as water, while graphene oxide (GO) and copper (Cu) are applied as hybrid nanoparticles. The flow is assumed to be in a steady state. The governing partial differential equations along with boundary conditions for the modeled problem … Show more

“…Hayat et al [3] analytically studied the radiative MHD flow of viscoelastic nanofluid and found that radiation helps to improve the thermal conductivity and temperature of the fluid. Articles of the implementations, formulation, and thermomechanical characteristics of hybrid nanofluids were already undertaken by the following researchers: Subhani et al [4], Qi et al [5] and Islam et al [6].…”
In this study, magnetohydrodynamic (MHD) three-dimensional (3D) flow of alumina (Al 2 O 3 ) and copper (Cu) nanoparticles of an electrically conducting incompressible fluid in a rotating frame has been investigated. The shrinking surface generates the flow that also has been examined. The single-phase (i.e., Tiwari and Das) model is implemented for the hybrid nanofluid transport phenomena. Results for alumina and copper nanomaterials in the water base fluid are achieved. Boundary layer approximations are used to reduce governing partial differential (PDEs) system into the system of the ordinary differential equations (ODEs). The three-stage Lobatto IIIa method in bvp4c solver is applied for solutions of the governing model. Graphical results have been shown to examine how velocity and temperature fields are influenced by various applied parameters. It has been found that there are two branches for certain values of the suction/injection parameter b: The rise in copper volumetric concentration improved the velocity of hybrid nanofluid in the upper branch. The heat transfer rate improved for the case of hybrid nanofluid as compared to the viscous fluid and simple nanofluid.

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 $${R}_{0}$$

“…Shah et al 7 deliberated thermal augmented EMHD micropolar hybrid nanofluid flow on a horizontal surface. Islam et al 8 surveyed the thermal flow for micropolar hybrid nanofluid (GO + Cu + H 2 O) flow amid two plates. The efficiency of hybrid nanofluid has been analyzed by Khashi’ie et al 9 with nanoparticles of copper and alumina in a base fluid taken as water.…”
The growth of hybrid nanofluids can be connected to their
enhanced
thermal performance as pertains to the dynamics of automobile coolant
among others. In addition to that, the thermal characteristics of
water-based nanofluids carrying three different types of nanoparticles
are incredible. Keeping in view this new idea, the current investigation
explores ternary hybrid nanofluid flow over a stretching sheet. Joule
heating and viscous dissipation are addressed in the heat equation.
Three distinct kinds of nanoparticles, namely, magnesium oxide, copper,
and MWCNTs, are suspended in water to form a ternary hybrid nanofluid
with the combination MgO–Cu–MWCNTs–H
2
O. To stabilize the flow of the ternary hybrid nanofluid, transverse
magnetic and electric fields have been considered in the fluid model.
The production of entropy has been analyzed for the modeled problem.
A comparative study for ternary, hybrid, and traditional nanofluids
has also been carried out by sketching statistical charts. The equations
that govern the problem are shifted to dimension-free format by employing
transformable variables, and then they are solved by the homotopy
analysis method (HAM). It has been revealed in this work that the
flow of fluid opposes by magnetic parameter and supports by electric
field the volumetric fraction of ternary hybrid nanofluid, while thermal
profiles are gained by the growing values of these parameters. Boosting
values of the electric field, magnetic parameters, and Eckert number
support the Bejan number and oppose the production of entropy. Statistically,
it has been established in this work that a ternary hybrid nanofluid
has a higher thermal conductivity than hybrid or traditional nanofluids.
