Speech Title: Magnetohydrodynamics (MHD)

Abstract: In the last decade, most of the industries invest their budget to use energy more effectively due to minimize dangerous effect of global warming. Highly efficient heating and cooling processes are essential to use energy more effectively. Therefore, the studies are carried out to increase the thermal performance of variety of energy storage systems including condensers, evaporators, and heat exchangers. While heat transfer enhancement is one of the priorities for many engineering applications where energy conservation and efficiency are important. Higher heat transfer capacities for these systems can only be achieved by using active and passive techniques. Researchers are trying to use different combinations between passive, active, and hybrid methods to increase the convective heat transfer performance of the thermal systems.

Fluid flow under the magnetic field effect is stated as Magnetohydrodynamic (MHD) phenomenon which is the field that examines the dynamic behavior of electrically conductive fluids. MHD received substantial attention from scientists and engineers in recent years. It is extremely relevant in many applications like some transformers, generators, accelerators, flow control as well as cooling/heating applications. The thermophysical properties of fluids, such as thermal conductivity and viscosity, may change under a magnetic field. The magnetic field intensity externally applied to the channel, on different axes, affects the velocity profile, flow rate, pressure, and temperature gradient of the fluid flow in the channel. Because of these effects, magnetic field application is attractive for flow control applications. In this way, its importance has emerged in many fields of industry such as heat exchangers, cooling of electronic devices, cooling processes in nuclear reactors, controlling liquid-metal fluids in the field of metallurgy. It has become the focus of researchers’ attention. Recently, studies in which both passive and active techniques are used together have been increasing contributing to the improve of the thermal performance of the studied systems. These studies, which can also be expressed as hybrid methods, are applications to increase the heat transfer that occurs with the combination of more than one of the passive or active techniques. The use of both nanofluid and magnetic field can be given as an example. Nanofluids, made of magnetizable metallic nanoparticles affected by a magnetic field, are expressed as ferronanofluid or magnetic nanofluid (for example, Fe3O4/water nanofluid). The main reason for heat transfer enhancement attained by this method is that nanoparticles approaching the channel surface due to the magnetic field form a chain-like structure and increase the local heat transfer coefficient. Studies carried out considering the hybrid method; require the joint solution of both the Navier-Stokes equations characterizing fluid flow and Maxwell’s equations, which is quite complex and characterizing magnetic field distribution. For this reason, many studies are conducted on mathematical models that can practically solve the MHD problems.
