  7. Abstract:
  8. Considering the fact that there is a blood flow inside the vessels it is possible that blood flow is always associated with fouling and this may decrease the blood flow when a blood vessel is injured, the cells of your blood bond together to form a blood clot. The blood clot helps you stop bleeding. Blood clots are made of a combination of blood cells, platelets (small sticky cells that speed up the clot-making process), and fibrin (protein that forms a thread-like mesh to trap cells). Doctors call this kind of blood clot a “thrombus.” We study the effects of different parameters on the deposition of Nanoparticles on the surface of a bump in the blood vessels by the magnetic field. The Maxwell and the flow equations are solved for this purpose. It is assumed that the blood is NonNewtonian and the number of particles has been considered enough to rely on the results statistically. Using MHD and its property it is possible to control the flow velocity, remove the fouling on the walls and return the system to its original form.
    In this paper, we will simulate two cases of magnetic fields. First we will consider the situation with constant magnetic field, and then we will simulate the case with varying magnetic field. The magnetic fields are magnitude of 0.5T, 1.5T, 2T and should be applied with a symmetric form Then we will release particles in a vessel using “particle tracking” and apply effective force such as drag force, Brownian and gravity .The released particles must be reactive to the magnetic field. In the initial set-up the surrounding tissue of the vessel will be air and the fluid will be blood, the equations are considered for Newtonian fluid. The grid in the simulations is made using “mapped meshing
