“…Many factors, such as the direction, the inclination of the magnetic field and the distribution of the magnetic field, will considerably influence the heat transfer enhancement in the presence of a magnetic field. Wu et al [30], Siddiqui et al [112], Singh et al [113], and Yousefi et al [114] considered the influence of magnetic field direction, magnetic field inclination angle and magnetic field distribution on the heat transfer of magnetic fluid. Wu et al [30] explored the influence of magnetic field intensity and distribution on magnetic fluid.…”

“…As for the magnetic field distribution, they found that the Nusselt number will be increased when the magnetic source becomes closer to the cold (hot) source and be instead decreased when the magnetic source is in the middle position. Siddiqui et al [112] investigated the flow of TiO 2 -water-based nanofluid in the existence of an oblique magnetic field and found, with the increase of magnetic field intensity and angle, the fluid speed of pure water and nanofluid decreases, but the temperature increases. The Hartmann number and Nusselt number increase with the magnetic field strength.…”

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.

Many chemical reactive methods, like combustion, catalysis, and biochemical involve homogeneous–heterogeneous chemical reaction (HHCR). The collaboration among the heterogeneous and homogeneous reactions is exceedingly multifarious, including the creation and depletion both within the liquid and catalytic surfaces. Here, we observe the influences of Cu and Al2O3 nanoparticles past an elongating sheet under HHCR. An inclined magnetic field with an acute angle is applied to the direction of the flow. Further, radiative heat, temperature, and exponential space‐based heat source aspects are modifying the thermal equation. The governing nonlinear equations are deciphered by utilizing the Runge–Kutta‐based shooting method. It is found that HHCR reduces the solute layer thickness, whereas the increase in the angle of inclination of applied magnetism thickens momentum layer thickness.

Re-engineering the channel heat exchangers (CHEs) is the goal of many recent studies, due to their great importance in the scope of energy transport in various industrial and environmental fields. Changing the internal geometry of the CHEs by using extended surfaces, i.e., VGs (vortex generators), is the most common technique to enhance the efficiency of heat exchangers. This work aims to develop a new design of solar collectors to improve the overall energy efficiency. The study presents a new channel design by introducing VGs. The FVM (finite volume method) was adopted as a numerical technique to solve the problem, with the use of Oil/MWCNT (oil/multi-walled carbon nano-tubes) nanofluid to raise the thermal conductivity of the flow field. The study is achieved for a Re number ranging from 12 × 10 3 to 27 × 10 3 , while the concentration (φ) of solid particles in the fluid (Oil) is set to 4%. The computational results showed that the hydrothermal characteristics depend strongly on the flow patterns with the presence of VGs within the CHE. Increasing the Oil/MWCNT rates with the presence of VGs generates negative turbulent velocities with high amounts, which promotes the good agitation of nanofluid particles, resulting in enhanced great transfer rates.
