内容記述 | This study deals with numerical simulation performed on pulsatile blood flow near a typical cerebrovascular branch with an aneurysm. Non-Newtonian properties of the blood is taken into account in this simulation by use of Carreau-Yasuda viscosity model. The aneurysm concerned takes the shape of sphere, this simple geometry being chosen for the sake of wide range of parametric studies. The numerical studies using a commerical solver CFX-5 (ANSYS), which employs un structured grid system with clustering of prism-type elements near the cerebrovascular artery and aneurysm walls, reveal the important effects of several parameters such as aneurysm angle or bifurcation flow ratio upon magnitude of wall shear stress and its gradient on the wall. Besides, an attempt is also made using several models of the aneurysm with different sizes to clarify how and to what extent the appearance of the aneurysm changes the flow field around the bifurcation without aneurysm. |
