Numerical simulation of the subclavian aneurysm blood flow

This paper reports an analysis of blood flow patterns that occur in a saccular subclavian aneurysm, by numerical, Galerkin finite element simulation. Investigations using image based reconstructed and CAD edited computational domains were also conducted on realistic blood vessels. We assume resistive type of vessels and use inlet pressure conditions rather than inlet velocity profiles to solve for the difficulties related to unknown velocity profiles usable as inlet BC. The results - velocity, pressure and stress fields - unveil insights in the flow dynamics within the aneurysm build-up and the flow-vessel interactions.
