Preliminary numerical study of the influence of realistic geometry of AAA on flow features.

Presents a study which compared the dynamics of a physiological flow in an idealized asymmetric geometric model of abdominal aorta aneursym and in a realistic one, evaluated the clinical pertinence of such simplified models, used in most of studies. Information on how the three-dimensional numerical simulations of physiological flow in both models are performed; General flow patterns generated by physiological flow in the idealized model; Determinant for the understanding of flow features.
