Abstract

The recent studies in biofluids of the cardiovascular system has put in front several apprehension for the diagnosis of atherosclerosis. Arterial stenosis is basically the fat accumulated over the inner walls of the artery. The stenosis are found mostly on the bifurcations of the large arteries and the junctions the curvatures. The stenosis is mostly found on the carotid arteries and its branches. This deposition occurs commonly in larger arteries, but the most probable locations for the development of stenosis correspond to the regions of curvature or branches in the vessels. Consequently, wherefore to understand the out-turn of a magnetic field (MHD) on blood flow through these arteries. The blood is modeled as unsteady, laminar non-Newtonian flow with pulsating pressure and with Magnetic field MHD. The governing equations were solved through FLUENT solver, which requires the domain discretization into control volumes. The arithmetic results are depicted graphically. The detailed investigation and analysis provides important acumen into the effects of magneto hydrodynamics on wall shear stress, blood velocity as well as pressure. It has been observed that presence of magnetic field reduces the flow characteristics. As the fixing of the stagnation regions inside the flow of the field can be used in medical field, via the application of the magnetic field, where the absence of that regions is seen. The present results agree with some of the existing findings in the previous literature.
