The purpose of this study is, from the hydrodynamic aspect, to accumulate data for prediction of rupture risk of a cerebral aneurysm. In branch flows, the authors' group pointed out that there is a possibility of growing aneurysm at the stagnation point or at the location slightly away from a stagnation point. Here the wall shear stress, one of important factors for the causes of ruptures, is investigated by two-dimensional numerical simulations and three-dimensional experiments in vitro with aneurysm models. The aneurysm at the branch point is called Model T. The distance between the axis of inlet pipe and the axis of aneurism is those of the radius or the diameter. The former is called Model A and the latter Model B. From the viewpoint of the effect of shear stress, Models T and A are dangerous.
