Resumo(s)

We investigate the effects on non‐Newtonian blood flow model on the wall shear stress (wss), velocity and viscosity distributions. The 3D Navier‐Stokes equations coupled with viscosity models describing the steady flow in Portal Vein have been solved numerically. Three blood viscosity models (Newtonian, Power‐law and Carreau) are used in numerical simulations. The results highlight the influence of these models on the blood flow and show that the viscosity model of blood may have significant impact on the numerical results especially in the region of the thrombosis.
