Mechanobiology of LDL mass transport in the arterial wall under the effect of magnetic field, part I: Diffusion rate

It is well-known that the Low Density Lipoprotein (LDL) can accumulate and penetrate into the arterial wall. Here, we have investigated the diffusion rate of macromolecules across the porous layer of blood vessel under the effects of magnetic force. By using a finite volume technique, it was found t...

Description
Summary:It is well-known that the Low Density Lipoprotein (LDL) can accumulate and penetrate into the arterial wall. Here, we have investigated the diffusion rate of macromolecules across the porous layer of blood vessel under the effects of magnetic force. By using a finite volume technique, it was found that magnetic field makes alterations in diffusion rate of LDLs, also surface concentration of macromolecules on the walls. As well, the influence of different value of Re and Sc number in the presence of a magnetic field have shown as nondimensional concentration profiles. Magnetic field considered as a body force, porous layer simulated by using Darcy's law and the blood regarded as nano fluid which was examined as a single phase model. •LDLs mass transfer across the arterial wall under magnetic field has simulated numerically.•Arterial wall assumed as a homogeneous porous layer by using Darcy's law.•Blood containing 4% Vol. Fe3O4 regarded as nanofluid and has examined by single phase model.•Magnetic field significantly affects the diffusion rate of LDLs through porous arterial wall.
