The arterial branch from abdominal artery to renal artery is one of the predilection sites of atherosclerosis. Hydrodynamic factor to the arteriosclerosis initiation has been elucidated about the steady flow In this study, we analyze the flow structure of renal artery branch during pulsatile flow. The renal artery branch from the abdominal aorta is modeled on the based of 3D data obtained from CT image. To calculate the wall shear stress, the velocity is measured at the distance of 0.6mm from the tube wall. The wall shear stress distinctly changes around the upstream comer. The large change of the wall shear stress along the upstream corner of renal artery would be closely related with the initiation of atherosclerosis from the viewpoint of hemodynamics.
