| Summary: | 碩士 === 國立臺北科技大學 === 機電整合研究所 === 103 === Hemodynamic factors are thought to be responsible for the localization of vascular disease in areas of complex flow in the coronary, carotid, abdominal, and femoral arteries. In those regions, these complex flow often occur due to branching, bifurcation, and curvature of the arteries. Unlike other areas, the infrarenal aorta is much less investigated due to its complex geometry. In the present study, a reliable numerical simulation technique was developed to study the flow fields of flow in a multi-branched tube, especially, in a model of abdominal aorta. We use computational fluid and solid model to predict the relation between inlet pressure and vessel wall deformation and stress. Also, the fluid solid interaction has been applied to more accurately predict the behavior of blood vessel.
