Abstract: Flow visualization in realistic models is very important for the
study of pathological vessel enlargements (aneurysms). Furthermore, flow
visualization may help in treatment decisions. However, the most interesting
parameter, the wall shear stress, is difficult to measure in vivo. This
parameter can be provided by computational fluid dynamics. However, the
numerical methods don't visualize the results as does of the dye
washout method – a method often used in flow studies. This experimental
method simulates the cine angiograms acquired during contrast agent injection
used in medicine. In this paper we present the dye washout visualization of CFD
results and compare these results with the conventional dye washout experiments
in the same aneurysm model under steady flow conditions.
