Abstract

Abstract

A numerical analysis of Newtonian and non-Newtonian flow in an axi-symmetric tube with a local constriction simulating a stenosed artery under steady and pulsatile flow conditions was carried out.Based on these results,the concentration fields of LDL(low-density lipoprotein)and Albumin were discussed.According to the results,in great details the macromolecule transport influences of wall shear stress,non-Newtonian fluid character and the scale of the molecule etc are given.The results of Newtonian fluid flow and non-Newtonian fluid flow,steady flow and pulsatile flow are compared.These investigations can provide much valuable information about the correlation between the flow properties,the macromolecule transport and the development of atherosclerosis.
