Abstract
Electromagnetic fields have many applications in medical science. It is essential to couple the ferrohydrodynamic (FHD) and magnetohydrodynamic (MHD) principles when magnetic fields are applied to blood as a biomagnetic fluid. The purpose of the current study is to investigate the effect of a nonuniform magnetic field on blood flow. To solve the nonlinear governing equations, continuity and momentum equations, a computational fluid dynamics (CFD) code based on finite volume is utilized. The code considers blood as a homogeneous Newtonian fluid. It also takes into account the magnetization and electrical conductivity properties of blood. The results show that for low Reynolds number the blood velocity shape changes near the magnetic source. In addition, blood pressure is maximum near the magnetic field and decreases when it is away from it. In addition, the wall shear stress, an important factor, increases rapidly near the magnetic source, especially when a high-gradient magnetic field is used.
