Plane Periodic Flow Predictions for Fusiform Aneurysms
Publication: Journal of the Engineering Mechanics Division
Volume 104, Issue 1
Abstract
Pathological bulges or dilatations of an artery are found in a variety of forms at diverse locations in the vasculature. In this paper, unsteady flow solutions in a two-dimensional wavy channel are obtained using the conservative form of the vorticity transport equation. A simple transformation is employed to shift the finite-difference calculations to a rectangular field where square meshes are used. The aneurysms geometrics selected for study showed that the main kinematic and kinetic activity was concentrated in the region near the cavity at all times except near flow reversal. At this time, the vortex that was created within the cavity and that had been trapped there were ejected.
