Abstract
Abstract Peripheral vascular diseases is one of the main causes of death in the world. It is disorders that cause the blood vessels to narrow, block, or spasm. Here, effects of two inclined rectangular permanent magnets field on heat transfer and flow characteristics of blood fluid in a channel, as a model of straight part of the aorta, has been investigated using FerroHydroDynamics (FHD) principles. Thermally and hydrodynamically fully developed flow is considered at the inlet of the vessel. Governing equations have been discretized using the finite volume method and the SIMPLE algorithm. Simulations have been carried out for different inclination angles of magnets and saturated magnetization. From the results, the magnetic field of two inclined magnets leads to increase heat transfer of blood fluid flow toward the walls. Moreover, major energy loss, arising from mean wall shear stress, is decreased but local or minor energy loss, arising from generated vortices, is increased. Furthermore, the formation of recirculation zones near the wall, where the magnetic drug can be trapped there for uptake to tissue, is observed.
