Summary: In this study, repeated flow-facing wedge-shaped protrusions are explored to enhance heat transfer behavior in quasi-two-dimensional magnetohydrodynamic duct flow. Various flow parameters were investigated to study their effects on heat transfer ratio and efficiency. The results showed potential for further improvement by optimizing geometric parameters such as pitch and wedge angle.

Summary: In this study, the MHD Casson fluid flow on a stretching/shrinking surface with mass suction/injection is investigated. The boundary problem is transformed from highly partial differential equations to ordinary differential equations using similarity variables. Analytical explanations are provided for the resulting ordinary differential equations by considering different controlling parameters and corresponding boundary conditions. The outcomes of the investigation, which can be analyzed using graphical form, reveal the behavior of transverse velocity and tangential velocity under different scenarios and parameter values.

Summary: This study investigates the influence of magnetic field on pulsatile blood flow and heat transfer in an artery with aneurysm using the mesoscopic lattice Boltzmann method. The results show that the application of a magnetic field enhances heat transfer in the inlet zone of the aneurysm, reduces recirculation zones, and increases wall shear stress, thereby preventing the progression of vascular diseases and rupture in the aneurysm region.

Summary: This paper examines the magnetic effects on Reiner-Philippoff fluid flow over a permeable shrinking wedge. It is found that the presence of a magnetic field can improve the friction factor and heat transfer performance, while increasing the suction strength has similar effects. However, increasing the Reiner-Philippoff fluid parameter lowers the heat transfer rate but increases the friction factor.

Summary: This study experimentally investigates the natural convection heat transfer in a three-dimensional I-shaped enclosure with wavy-walled and inner circular pipe. One layer is filled with Al2O3-water nanofluid while the other layer is filled with nanofluid/porous medium. The thermophysical properties of the nanofluid are measured, including thermal conductivity, viscosity, and density. The experimental results show good agreement with the calculated properties based on theoretical models within the studied nanofluid concentrations. Thermocouples are installed to measure the temperature, and magnetic fields are applied to observe the slight increase in temperature. It is also found that increasing the hot side wavy-walled temperature leads to an increase in the temperature difference in the nanofluid-porous region and the nanofluid region.

Summary: The study investigates thermal phenomena during MHD free convection in an oblique enclosure filled with a Cu-Al2O3/water hybrid nanofluid. Results show that increasing heating surface area does not always improve heat transfer, while increasing undulation amplitude can enhance heat transfer up to a certain optimal value. Heat transfer enhancement is influenced by the wall curvature at higher Ra-m, lower Da and Ha, and lower volume fraction of nanoparticles.

Summary: This study investigated the dynamic spatial-temporal characteristics, evolution processes, and transport mechanisms of gas-liquid metal two-phase flow with and without an external magnetic field. The presence of a magnetic field reduces the capacity of gas to carry liquid metal, but smoothens the deformation of the phase interface. In the absence of a magnetic field, an increase in the inlet gas volume fraction enhances flow instability.

Summary: This article investigates the modeling and numerical simulation of Magnetohydrodynamic (MHD) buoyancy driven convection flow in a differentially heated, square enclosure. Numerical solutions are computed for different values of Rayleigh number ranging 103 < Ra < 107 and Hartmann number ranging 0 < Ha < 40. Comportment of MHD free convection heat flow from transient to steady state is numerically examined for a period of 0 to 1 s. It is seen that with increasing values of Rayleigh number there is increase in local Nusselt number distribution on heated side of the cavity, while velocity distribution in the flow domain decreases with increasing Hartmann number.

Summary: The article explores the magnetohydrodynamic fluctuating free convection flow of incompressible electrically conducting viscoelastic fluid in a porous medium under the influence of a pressure gradient and a magnetic field. Exact analytical solutions for velocity, temperature, and concentration distributions were obtained using Lighthill's method, with discussions on the physical implications of inserted parameters. The study also highlighted the reduction of the general solution to a Newtonian fluid when the viscoelastic parameter tends to zero, demonstrating the validity and correctness of the obtained solutions.

Summary: Recent studies in thermal engineering found that there is little research on employing nanofluid as a working fluid in a specific channel while considering both turbulators and magnetic field effect. This review focuses on the single and combined effects of nanofluid type, volume fraction, channel and turbulator geometry, magnetic field type, and flow regime on the heat transfer enhancement of these systems.
