Abstract

It has been a goal for many decades to develop a detailed model of the aortic artery that includes a couple fluid/wall interaction that is time dependent and three-dimensional. Simple models of the large arteries have yielded valuable information, but the complications of coupled time dependencies, three dimensionality, and wall elasticity are needed to compare with actual diseased states. Our paper presents some of the first results for the full unsteady and three-dimensional Navier-Stokes numerical calculations which are coupled to an elastic model for the geometry of the thoracic aorta. The numerical models we have developed have the capability to include with increasing fidelity a detailed description of a large part of the aortic flow system.
