 note = {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.},
