Abstract : The computational fluid dynamics simulations (CFD) has been carried in an idealized curved section of human coronary artery using multiphase transient, pulsatile and non-Newtonian flow. The study of behavior of affected flow regions of blood cells in arteries has significant impact in understanding atherogenesis. The non-Newtonian model is applied to fluid dynamics approach consisting of plasma, RBCs, and leukocytes was studied to arrive at numerical simulations of local hemodynamics in a flow regime. This CFD model study helps in finding the flow patterns, phase distributions and wall shear simulate and to examine the behavior of fluid, and find out that it depends on both volume fractions and shear rate of RBCs and leukocytes. The migration and segregation of blood cells in arteries were computed. When higher leukocyte concentration was predicted, it was correlated with relatively low WSS near the curvature having a high wall shear stress. This action is mainly due to flow-dependent particle interactions of the leukocytes with RBCs in pulsatile flow. This multiphase hemodynamic analysis will be of great help in following the mechanism of plaque formation in arteries with in vivo complex flow conditions.
