Blood Flow Analysis Using Medical Imaging Data and Streamline Visualization
A numerical simulation of blood flow in the thoracic aorta is presented. Patient-specific aorta shapes are used in a centerline-fitted curvilinear coordinate system in which the Navier–Stokes equation is discretized using finite-difference approximation with immersed boundary method. Numerical results are visualized by drawing instantaneous streamlines to exhibit the flow structures. Dean vortices and the transition from them to a swirling flow are observed by comparing the original shapes and projected shapes that have no torsion.
