摘要：

The objective of this work was to simulate Blood flow through a three-dimensional aneurysm and to study particularly the influence of expansion ratio and eccentricity of the aneurysm on wad shear stress and pressure distributions. The non-Newtonian Behaviour of blood viscosity was considered (Casson model). Numerical simulations were performed with a finite element package FIDAP7.6. The results showed existence of local maxima of shear stress and pressure near the end of aneurysm. These maxima could be a mechanical Refer involved in the rupture of aneurysm. It also should Be pointed out that in the range of geometric parameters and now rate considered the non-Newtonian effects could be neglected.
