The Blood Flow Simulations of Human Aortic Arch Model with Major Branches
In this study, we use the Computational Fluid Dynamics (CFD) Aortic Geometry Extraction Techniques to study the blood flow through the human aortic arch geometry, which is constructed from a set of CT images. The CFD simulation uses the commercial ANSYS 13 based on a finite volume method for solving the Navier-Stokes equations. The simulation is conducted to understand the flow characteristics in the complex geometry, including three major branches located at the arch, strong curvature, and tapering. We show the general Wall Shear Stresses (WSS) distribution of aorta, which exhibits strong curvature effects near the arch. The velocity field in the ascending aorta is severely changed by the non-planar curvature, while the WSS is affected by the mechanism in the development of atherosclerotic plaques.
