Human's Ascending Aorta have torsion. It is known Aneurysm patient's torsion of Ascending Aorta is generally larger than healthy person's one. We made some kinds of Aortic Arch models have torsion, and calculated blood flow in aorta. We researched how the size of torsion affected blood flow and wall-shear stress. The location of Arteriosclerotic Disease was compared with points blood flow and wall-shear stress were changed. As a result, we obtain tendancy of distribution of wall-shear stress by the torsion.
