Rapture of cerebral aneurysm is strongly associated with subarachnoid hemorrhage. The medical statistics indicate that cerebral aneurysm occurs predominantly in the arteries of branching with sharp curvature where flow and wall shear stress change abruptly. In this paper, the numerical simulation has been conducted to investigate effects of curvature on the flow pattern in the artery. The results have shown the periodic oscillations in the flow field, which is correlated with transient behavior of secondary flow and separation. The details of flow behavior such as effects of curvature were visualized using the commercial software FIELDVIEW.
