“…The subject of magnetic field effects is very wide. In addition to uniform magnetic field effects, researchers also study non-uniform magnetic fields and possibilities of their influence on chemical processes [5][6][7]. Inhomogeneous magnetic fields may cause changes in fluid flow, concentration, and convection [5].…”

The paper presents and summarizes some research on constant magnetic field effects in chemistry. Metals and alloys electrodeposited under constant magnetic field have greater thickness and smoother surface with finest grains. Metallic materials deposited under the influence of uniform magnetic field may have stronger corrosion resistance, than those obtained without the presence of magnetic field. Constant magnetic field also causes an increase of the electropolymerization rate and yield of some organic reactions. Our research also shows that the presence of constant magnetic field affects the electrodeposition process of alloys and their morphology to a great extent. The effects of magnetic field on metals, alloys, composites, polymers and other materials are due to the Lorentz force and the magnetohydrodynamic effect. It is possible that the further development of magnetoelectrodeposition will allow for using the constant magnetic field to improve the properties of metal coatings, alloys, polymers, and other materials in the industry.

“…Improving the thermal-hydraulic performance of heat exchangers has been a topic of interest to many engineers. Increasing heat transfer is possible by techniques such as changing the geometry of the pipe [1], using nanofluids [2][3][4] and applying external electromagnetic energy [5][6][7]. The use of fins on the tube [8][9][10], rotation of the crosssectional area of the pipe [11,12] and flattening it [13,14] are methods of increasing heat transfer by changing the geometry of the tube.…”

In this study, the effects of the presence of multi-longitudinal vortex and various rotation angles between the pitches of alternating elliptical axis (AEA) tubes on heat transfer and pressure drop of turbulent flow were numerically investigated. Turbulent flow of water fluid was simulated at Reynolds numbers of 10,000-60,000. The turbulent flow and heat transfer in the tubes were discussed in terms of parameters such as static pressure, velocity magnitude, wall shear stress, turbulent intensity, performance evaluation criterion and the field synergy principle. The results demonstrate that most heat transfer occurs in the transition zone, but this also caused a high rate of pressure drop. Increasing the rotation angle between pitches from 60°to 80°increased the heat transfer, which increased the number of the multi-longitudinal vortices from four to eight and better mixed the cold fluid with the hot fluid near the tube wall on more paths. The friction factor decreased and the average Nusselt number increased as the Reynolds number increased. Both parameters increased as the angle of the pitch rotation increased. The performance evaluation criteria for all AEA tubes at a constant pumping power showed that the highest value (1.09) was achieved at a low Reynolds number (Re = 10,000) in the AEA 90°tube.

They showed that the computational grids must cover the magnetic force accurately.…”

In this paper, biomagnetic fluid flow in a three-dimensional channel in the presence of obstacles and under the influence of a magnetic field is studied numerically. The magnetic field is generated by a wire carrying electric current. The mathematical model of biomagnetic fluid dynamics which is consistent with the principles of ferrohydrodynamics and magnetohydrodynamics is used for the problem formulation. A computational grid which accurately covers the magnetic force is used for the discretisation of computational domain. The flow field is studied in the different arrangements of the obstacles and diverse magnetic field strengths. The results show that the flow pattern is drastically influenced by the applied magnetic field. Applying the magnetic field causes a secondary flow that affects the velocity distribution considerably. The magnetic force also reduces the maximum axial velocity. Furthermore, the magnetic field has a considerable impact on the recirculation zones behind the obstacles. The magnetic field makes the recirculation zones smaller. This study indicates that applying the magnetic field increases the axial drag coefficients of the obstacles significantly (in a case, by 40.15%).
