We analyzed the blood flow inside blood vessels by computational fluid mechanics to investigate the fluid mechanical effect of the blood flow on the arterial wall with respect to various pathophysiological phenomena. We built 3D-computational fluid mechanical models to model the symmetrical and asymmetrical configurations and carried out computation using the models under steady and unsteady flow conditions. It was confirmed that no flow separation occurred at either the inner or the outer curvatures of the 3D-bifurcation models. Remarkable differences of the spatial pattern of the wall shear stress were found between the pulsatory flow and the steady flow computations.
