AbstractIn this study, Lumen Surface Concentration (LSC) of Low Density Lipoprotein (LDL) particles in arteries with a permeable wall and up to 60% stenosis under steady state conditions, for Newtonian and non-Newtonian fluids, has been numerically investigated. The results show the Concentration Polarization (CP) phenomenon. Also, an increase in wall suction velocity (high blood pressure) and a reduction in Wall Shear Stress (WSS) are introduced as factors for an increase in LSC. Maximum LSC are observed for 40% stenosis.
