To achieve it, we combined the CFD techniques with imaging techniques; this allows us to approximate the blood flow real behavior. The aortic arch has a complex structure, with bifurcations, non-planar curvature, varying cross-sections. Understanding the effects of the curvature on the flow is an important task, to measure and interpret human hemodynamics in the aortic arch like flow axial velocity, vorticity and wal shear stress. For this reason, we initially studied the effects of curvature on the flow, creating a simplified model of the aorta(called candy cane), with a 180 planar bend. In the first part of the thesis we show the effects of the curvature on the simple model using a steady inflow. Since in real cases the blood flow is not steady, we study the effects of a pulsatile flow in a candy cane. Comparing the results of the candy can...
