Numerical simulation of LDL particles mass transport in human carotid artery under steady state conditions

In 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.
