“…The micropolar effect parameter, ε (= η 1 /η), is related to almost all terms of Equations (28) and (29) as it is connected to the Newtonian kinematic viscosity and the vortex viscosity coefficients. It is studied here in the range of 0 < ε < 1.…”

“…Recently, Jaiswal et al [27] presented a two-fluid model of blood flow through a porous layered artery in the presence of a uniform magnetic field transversely applied to the direction of blood flow. Blood was assumed as a micropolar fluid in the core region and plasma is treated as a Newtonian fluid in a second region of the artery, which comprises 55% of blood volume [28]. Analytical solutions of the flow velocity, microrotation, flow rate and stresses at the wall through the composite porous walled artery were obtained.…”

“…The importance of this investigation is reinforced taking also into account the ongoing usage of magnetic fields in biological fluids, which are described as micropolar. The applications of this include magnetic targeted drug delivery systems [32], magnetic hyperthermia for thermal ablation of cancer cells [28], and lessening of bleeding in surgeries [33] to mention but a few.…”

Micromagnetorotation of MHD Micropolar Flows

The studies dealing with micropolar magnetohydrodynamic (MHD) flows usually ignore the micromagnetorotation (MMR) effect, by assuming that magnetization and magnetic field vectors are parallel. The main objective of the present investigation is to measure the effect of MMR and the possible differences encountered by ignoring it. The MHD planar Couette micropolar flow is solved analytically considering and by ignoring the MMR effect. Subsequently, the influence of MMR on the velocity and microrotation fields as well as skin friction coefficient, is evaluated for various micropolar size and electric effect parameters and Hartmann numbers. It is concluded that depending on the parameters’ combination, as MMR varies, the fluid flow may accelerate, decelerate, or even excite a mixed pattern along the channel height. Thus, the MMR term is a side mechanism, other than the Lorentz force, that transfers or dissipates magnetic energy in the flow direct through microrotation. Acceleration or deceleration of the velocity from 4% to even up to 45% and almost 15% deviation of the skin friction were measured when MMR was considered. The crucial effect of the micromagnetorotation term, which is usually ignored, should be considered for the future design of industrial and bioengineering applications.

“…MHD also referred to as hydromagnetic includes plasmas screens, metals oxides, and sea water or other conductive substances. In the analysis of nanofluid‐related fields, the inevitable, unavoidable, and nuanced applications of MHD nanofluids have drawn the interest of many researchers 11 . Bhatti et al 12 explored the diffusion‐thermal and thermal‐diffusion effects on a hyperbolic tangent nanofluid with MHD past a nonlinear porous stretched surface using the RK Merson method.…”

A numerical investigation is conducted to review the entropy study of magnetohydrodynamic (MHD) convection nanofluid flow from an inclined surface. In evaluating the thermophoresis and Brownian motion impacts, Buongiorno's model is applied to nanofluid transfer. Using Keller's implicit box technique, the governing partial differential conservation equations and wall and free stream boundary conditions are made into the dimensionless form and solved computationally. For different thermos physical parameter values, the numerical results are discussed both graphically and numerically. Verification of the present code with previous Newtonian responses is also included. To analyze the variability in fluid velocity, temperature, nanoparticle volume fraction, entropy, Bejan number, shear stress rate, wall heat, and mass transfer rates, graphical and tabulated results are reported. The study suggests applications in the manufacturing of nanomaterial fabrication, and so on.

“…Moreover, Wang et al [10][11][12] explored the application of the Al 2 O 3 -water nanofluid to a microchannel heat sink (MCHS), and the results depicted that the application of nanofluid can improve the thermal efficiency of MCHS, thus ensuring the working temperature and photoelectric conversion efficiency of solar cells. Nanofluids are also used in cancer treatment [13][14][15], wastewater decontamination [16], solar distillation system [17], engine cooling system [18], micro high strength refrigeration system [19].…”

A Review on Heat Transfer of Nanofluids by Applied Electric Field or Magnetic Field

et al. 2020

View full text Add to dashboard Cite

Nanofluids are considered to be a next-generation heat transfer medium due to their excellent thermal performance. To investigate the effect of electric fields and magnetic fields on heat transfer of nanofluids, this paper analyzes the mechanism of thermal conductivity enhancement of nanofluids, the chaotic convection and the heat transfer enhancement of nanofluids in the presence of an applied electric field or magnetic field through the method of literature review. The studies we searched showed that applied electric field and magnetic field can significantly affect the heat transfer performance of nanofluids, although there are still many different opinions about the effect and mechanism of heat transfer. In a word, this review is supposed to be useful for the researchers who want to understand the research state of heat transfer of nanofluids.
