This study focuses on the renal artery hemodynamics by using an integrated aorta model A with multiple branches up to nine and an isolated model B with an abdominal aorta and two renal arteries. These anatomic models are built up based on a Voxel-Man 3D Navigator while they are coupled with a lumped hemodynamic model for the 0D-3D coupling. The computed results demonstrate that there exists pronounced discrepancy of hemodynamics between the model A and B. in terms of intravascular flow patterns. the distribution of wall share stress (WSS) and. in particular. the oscillatory shear index (OSI) that is always referred to as an important hemodynamic factor dominating the onset of atherosclerosis or aneurysm.
