Unsteady blood flow in the stenosed artery subjected to magnetic field and injected nanoparticles

The blood flow in the stenosed artery was investigated in the current work. The blood, which was modelled as Newtonian or non-Newtonian fluid, was subjected to an oscillating pressure gradient and a periodic body acceleration. In the first problem, the magnetic field and the porosity were considered...
